I have no idea what “Twilight Sun” or “USDF” are, but I do know that this hardsuit by Luke Lyons (Tac) has more greeblage than is absolutely necessary. In some cases, too much of a good thing is still a good thing.
The little red HUD adds a splash of color, and even the feet have guns.
Of _course_ an Orkish mech has foot guns. MORE DAKKA!
I think if more colors had been used it would have masked the quality of the build. All gray shows off the detail in a rare beast: too much greeble and just one color = awesome! You don’t see that often at all and it’s really hard to achieve if you try.
