Haven't done any pixel art lately, but today's theme and restriction from @pixel_dailies motivated me to do something. The theme was Tank and the restriction was 5 colors (added transparency for the one i'm posting here).

I think I prefer doing geometric shapes, and this type of tanks are basicaly various shapes stacked on top of each other.

For the palette, I started by googling yellowish/green palettes and found this piece from Elastico-Gadget. I used the 4 colors in his fences and added a darker green. Don't think I ever worked with such a limited palette, it's challenging but fun.
