Really nice. Clean, simple, not too flashy. Color is good as well. Would love to see alternates of this design. Maybe standing on some kind of "base" or line for reference? The toe idea is a bit feminine but I think that's the nature of the beast. Good work!
#21 I still like #12 best. The curves don't add anything in my view. #21 is simple and clean. I would like to see alternate uses of the feet or even try shoes. Thanks!!
