I love it!
I agree with
Ikuto Akihiko: in everything she said. Not all great art is proportional, and there is a feeling of texture in it... To me, it feels like water color, I love the brushstrokes on the outline, skin, and dress (you can really see it there). Great mix of colors, and the the light pink background, as it gets lower on the picture, the darker the colors become. I see something that I often did when I was painting, I'd paint from the head down, like gravity, pulling the paint down from the top, just like how hair flows down.
Again, I love it, keep it up.
