I don't know how you did this but its awesome. Every little pixel is at the right place, every color is just gives better quality to the picture. ^^ Just keep this quality for your future pictures too. I want to see more masterpiece. (Why my text is too short. ._. I like to write short messages and I hate the too long ones. Eh, whatever i just write this because this message is too short so i need a longer one). Well, whatever, maybe I will ask you to do a background for me in the future, if you want it. ^^
First off, the overall composition of this picture is very nice! There's a dreamy air to it, what with the light shading around the borders and the soft, background. I really like the way you did the skies and trees, and how the flowers stand out from that because of the colour difference. I think there could have been a little more detail added to the flowers though, just to make it that much better
The girl looks very innocent and her expression matches that, along with her attire. The anatomy for her left arm looks a little bit off though...it stuck out and caught my eye when I was looking at this picture.
But overall, a very good job. The shading and colours all look great Can't wait to see more of your work!
