That doesn't look bad
Can you post the reference?
I think generally you should keep detail low in the body, because it's not the focus.
The fabric looks pillowshaded, but without seeing the ref that's hard to tell. I'd like to see simpler, clear-cut folds and shadows, and a more obvious light source.
I'm no fan of outlines either, especially the inside ones. This piece could probably do without them altogether.
Also there's a lot of
banding going on. Check it!
