Good work so far!
I like the hands on the left better. They look more like feathers, and have more style. I’d consider making that area slightly bigger though. Proportion-wise (visually, not anatomically) I think the hands, reaching back through the arm could be bigger. Not longer, just wider in the other 2 axes.
BTW, the textures so far look photo-sourced. Is that the direction you’re going with the rest? I think this concept could look really nice with a painterly look to it, like a childrens novel, although if you manage a fairly realistic look, that’d suit it too…
