Forgot to post this project I started while sculpting the lizard.
I wanted to get out of my confort zone so I tried to do a cartoon character inspired by Disney Infinity's style.
... namely, Luke Cage's right foot seems turned too much. Maybe turn the foot to the left a little or reposition the calf, so it isn't so out-of-line with his knee. Also, it might be good to lift the heel, so the right foot is balanced on the ball of the foot.
As for looking like a Disney Infinity character, you need to push the stylization more. Since it looks like your normal style is realistic, it might take more experimentation until you find your equilibrium.
