Hey I don't know if you are still making tiles for members that request them but if you are, could make some top-view turret tiles, The palette I am using is classic but with lots of added colors (Greys, Silverish, Yellows, Greens, Reds and Blues).
Machinery? I have zero experience with that XD. Would be a nice little experiment, but I don't think I can do it justice in Classic without prior practice.
Who wants to see these finished at some point?
Facts
-Will use Z3 animation if so. Drawn so that there is a free pixel vertically for bobbing.
-Hatless version would be made alongside, if so.
-Currently uses only 14 colors, including the transparent color. There's still room for 2 more.
-Will include misc. poses, if so.
