I'd say the proportions look phenomenally well done! If it's one thing I'd critique would be the characters left cheek bone in the painted piece. Something about the facial skin tones seem off, it looks as if the cheek is discolored from bruising(That's probably just me though.) Also, this may be a oversight on my part, but her right brow ridge looks as though the lasso tool was used to adjust proportions but was never painted in to acuminate that edited. As for the clothing, the highlights on the jacket are solid, but I would suggest trying to make the shadow parts just a bit brighter, as it looks as though the fabric pieces under her arm absorb all light that make contact with it. Of course, not all these critiques have to be taken, you can very well take this with a grain of salt. Thanks for your time! and happy artist-ing!
