If it weren't for the hair (and your signature poking in at the corner) I'd assume this to be a photograph- and not that the hair's not Stunningly well-done (and much Much better than I could manage in paint), but it just doesn't have the Hyper-realism of the rest of the piece. Something with the depth (of the curl of the hair on the right) and the too-perfect curls in general just sits wrong with me. The Lace however, and the necklace are utterly Breathtaking in their level of realism. Could I achieve that level or accuracy with paint, I would die happily. Overall, congrats on a masterful piece.
The details in the lace leave me speechless. The golden effects in the jewels, the smooth aspect of the skin... This is truly amazing. I can't find the right words to express the way I'm impressed ! Great job !
