I like it, she's beautiful.
She looks older, more mature, womanly. I like this picture for that reason. She doesn't look like she's just some girl at all. She looks regal, like a duchess or lady of a castle. She doesn't look innocent either, something I usually don't mind and kind of respect, but i feel as though i needed a change from. It doesn't look pornographic either, another plus. I'm going to favorite this pic and you as an artist, but only if you promise to make more art like this! I would love to see more angelic women like this. And try some back grounds! I would like to see where you imagine her being. I'm thinking a castle, tower, or maybe even a mountain. Also, i don't mind more than one girl in the picture, i think that could help enhance the art. Keep it up, please.
You have a real talent for this, keep it up!
