The volume and shine on her left arm works so well. But, by not defining the shadow under her head more, since the rest of her body is to heavily highlighted, the red tone does not suggest the shape of a proper head. The area from just under her chin and up to her ear gets a bit flat.
Thank you very much I totally understand what you mean I tried so hard to fix it In the end I wasn't too happy with the way it turned out but it was sooo much fun to paint there where so many colours in those shadows
As always, great work. However, since you're requesting critique: It seems to me like her head might be too small for her body. And that arm looks pretty chunky. But I don't know, maybe that's just what she looks like. Love the colour and texture on her face, though.
