Isn't she beautiful! What I love most about this piece is those flowing and organic lines. It reminds me of Alfons Mucha's "Le Soir" and "Le Nuit." I love the piece, but I feel a little off at the composition... the tree branch for me interacts in a strange way with the geometric forms in the border. (It curves in an interesting egg shape though.) Maybe you could resolve it by making other branches that reach further up and the composition might not feel so cut-in-half? I think it would serve to break up the space and connect her and the tree with the background. That just the advice though!
It's a lovely piece. It's cool to see one of your pieces before it's colored!! Your technique and the differences in line quality are beautiful.
I see the Mucha but I get a sense of Escher when looking through the hole but not Escher. I don't think that was intentional. Am I wrong? Man, your details raises the bar on my details. Now I know the skills better of the master.
