She is beautiful! Unfortunately, your photograph has some banding and artifacting to it. I'm sure if you ask after the challenge, someone will help figure out what's causing that, since this is really a wonderful portrait.
Not bad but too noisy and not sharp enough for my taste. Think this would have appealed more to me in b/w and with more contrast and sharpened a bit more, that would also make the noise seem more natural.
Nice capture - But it looks like it is a copy of another photograph? odd lines running across the picture - The blacks need more depth and it's a tad soft.
