Fabulous work! She looks really gorgeous! You could try to scan it in black and white, to avoid the stains. Of course it's up to you, it gives the work a feeling of going back to those times and shows its original. It's a freakin awesome piece, she looks so real! Amazing job, as usual!
well done. you captured her perfectly, and what's good is the fact that i've seen other people try to draw celebs and they dont look like them much. there's no mistake on this. your talent is endless. brilliant.
