I love the pose! Her legs look so cute! I love all of the sparklies and glitteries and all of the little details! Its so amazingly cute! I love her haircolour and outfit... her face looks so serene! I love the textures in the background as well. My only crit is that the piece seems to be fighting with itself a bit for attention. I would have toned the background down just a bitttt so that the girl stands out more
If she was a little bit taller I might consider....
.... well, you get the idea.
Good work, beautiful picture all around!
