Like this one, it’s made of “squished” spheres, The claws are rounded triangles. And the arms are smooth cylinders with a spherical rounded end.
I guess what I’m trying to say is make them have a little more depth? With creases, maybe more complex hands, etc.
They look a lot like Pokemon, is that the cartoony look you’re going for? If so I would like to say they look a little un-proportionate. (This is my first reply, please say anything that I should change in a reply to this reply.)
