It might just be the awkward angle that Simon's lower body is at, but neither of his feet seem right to me.
I think...his right foot should be pointed a bit lower and should be a bit larger. At the angle Nia's dragging him at, we'd likely be seeing more of its side than the bottom. In the first post, the extra foot would fit better, but its angle is also a little off. Like, it's pointed too far away from the viewer.
Now, Simon's left...well, leg and foot, actually, seem to be off. If you don't mind, try a quick sketch where we see more of the leg's inside than the outside. Just sorta take the whole leg from the hip and rotate it a bit so that the heel is closer to the center of the body.
Those are my two cents. I think it's amazing, to be honest, and far better than what I could ever accomplish (but you asked for an honest critique and you deserve one). Nia is positively adorable.
I can't wait for the finished work!
