Let the works speak for themselves. Sure I’ve learned tons seeing parts used and combined in ways I didn’t know, but the elitism, one-upmanship, cliques, and troll-like comments left a bad taste in my mouth.

It’s a fair bet that if I post something I’ll welcome suggestions that I’m unlikely to have thought of myself and will potentially improve my model. I might not always agree with the criticism but if it’s polite and sensible I’ll always appreciate.

In regards to research, I am typically OCD, gathering as many pictures as I can and then extrapolating the best representation. This sometimes leads to a bit of backlash, since I tend to work very hard to get pictures others did not know exist, so everyone else ends up basing it on one image set while I base it on a high-resolution blueprint of the original.

Usually the only constructive criticism that I get is from my closest friends, otherwise it is usually just negative and hateful. For an extended period, it drove me from the hobby and from public interaction in general within the community. Even now, I am hesitant to post anything again for fear of ridicule.

I think it largely comes from my past, but I lack the fortitude to have someone tear apart something I poured every ounce of my skills into. I am not one of those that subscribe to the “If you can’t say anything nice, don’t say anything at all” mindset, but rather the “If you have no reason to say something cruel, don’t say it at all” mindset.

So altogether, my experience is research and plan as much as possible, but know when to stop researching or you’ll never actually start the project, and never listen to anyone in regards to criticism until they have been your friend for over a year or two.

That’s not an absolute rule, though. The Ringworld would not be turning out half as good as it is without feedback from the WIP shots. I was originally planning on making all the landmasses and oceans on the inner ring a flat mosaic of tiles. Suggestions from people like Nathan Proudlove convinced me that I should try to sculpt exaggerated elevation instead, and once I tried it there was no going back, even if it did dramatically increase the complexity of the build.

Bird’s Eye is another good example. At one point on the WIP pics Mainman noted a place where the studs were throwing off the sense of scale, and I replaced the plates with Brassoed trans-blue tiles and it significantly improved the end product. Who knows? Maybe it made the difference in the contest.

Part of the problem is also that–quite honestly–most of the criticism you get on Flickr or other online communities is really not worth much. People post meaningless ratings with no objective frame of reference (like 6/10–what do “6″ and “10″ really mean?), nitpick details that make it obvious they haven’t read the description and/or don’t have any idea what you’re actually going for, or make inapt comparisons with no real substance behind them. And that’s just the criticism–the compliments aren’t much help either, as happy as I am to receive them. I’m glad it’s “awesome”, “epic” (talk about a word that’s on the verge of being overused to the point of losing meaning), or “well played”, and I’m as guilty as anyone of popping off one-line compliments–but it doesn’t really help me improve.

Now, as to research–that’s a subject close to my heart. My Google-Fu and Wikido are strong, and I am selectively picky about details. :) Whenever I get an idea about something that’s at all based on a real-world or fictional source, I go hunting for reference material. Probably the best example of this would be the PM Roof Support, which I built after digging up dozens of images of actual roof support equipment and spending far too much time surfing mining supply sites. If you spend enough time at it, you’ll often end up with inspiration for more ideas out of this process–I ended up with dozens of images for all sorts of heavy mining equipment that await the next time I get the urge to build Power Miners.

The amount of reference hunting I’ve been doing has only skyrocketed since I started doing custom Brickarms and minifigs. The Customs set on my photostream is the result of hundreds of hours–literally–of hunting down reference photos, watching Youtube videos of actual weapons being fired, and digging through Wikipedia and world-guns.ru. At any given time I have about ten or twenty browser windows open with images and sites related to whatever builds I’m working on at the time, and never have I been so grateful for the way Firefox preserves your tabs between sessions. :)

Anyway, that’s a big wall of text. tl;dr: With a few important exceptions I don’t get much useful criticism, mostly because my best builds are the result of banging it out all in one sitting from inspiration. Research, on the other hand, is huge, especially if you’re basing something on source material of any kind. Cue parade of self-serving examples.

As for me personally, I tend to build things without an historical origin, so I rarely have to deal with comments about “accuracy”, but I do believe that if you’re going to try to build a copy of something already existing, that you should try to get it as close as you can…otherwise why not just build something completely innovative? :P That leaves people with mainly the critique outlet of aesthetics. Often I intend something to have a certain look that doesn’t necessarily agree with the personal aesthetics of someone else, though it usually feels a bit like a cop-out using the “But that’s how I intended it to look” justification. Ultimately though when it comes down to pure aesthetics I still appreciate the criticism and comments; even if I don’t use it on the MOC it was suggested on there’s a good chance I’ll apply the basic principle in a future MOC.

In the end I think proper constructive criticism is a fine line that many people fail to walk correctly. You can point out mistakes or possible improvements, as long as it’s not overly attacking, and provides at least some helpful advice so it’s clear there has been SOME level of thought involved beyond “imma go troll lol”
