There's some issues with female head. Draw her skull on top of the painting to figure out what's wrong, her neck is very long, plus here secound hand is missing. i know you've wanted to hide it behind here body put still we should see here at least here arm. Side of that you could also recrop the image a it. her head is very close to the border of the image. It creates a tangent which you always want avoid. There's probably more issues but i'll stop here. It's still a good image, it simply needs some fixing ;3 cheers.
