Sweetly Wicked

I love the expression! This is gorgeously realistic. Nice title too.

Some of the details in this are great. I particularly like the tattoo and the silvery hair-like bits around her face. Although the tattoo doesn't seem to quite match the style of the rest of it - the edges are a bit soft in the rest of the picture (look around the lips and mouth to see what I mean) but the tattoo is quite clearly outlined.

I like the way you've used tones in this - she looks very cold, like a sort of ice queen. Makes her look more like a witch so nicely done.

I had something else to critique as well but I can't for the life of me remember what it was so I will say in the reply if it comes back to me!
