Unfortunately, I can't do that any time soon. If it's that important, I can release a black and white version of this but I haven't heard that much clamoring for it. This was just a quirk of the commissions process where I was open to upgrading it to a colored piece at the time, unlike the others which were priced as black and white sketches.
her knees and ankles bother me though. With her arms you can kinda see how everything is able to move, same with her neck and hips, but from the thighs down things look less detailed and like they can't move much.
I see where you're getting at. The other Robot Senshi designs feature more segmented legs and feet but here I felt like retaining a more natural look and wanted to continue emphasizing the upward momentum of her legs. So minimizing or accentuating the shape of her joints may have resulted in less believe able metal parts unless it was some sort of new alloy.
