Really not bad for a first attempt! :) Seems you caught the cursor in the image, but apart from that it looks pretty much pixel perfect. Some more shading on the ground/plants, to match the level of the character, would be nice, but form's all good.
I assume she's holding her arms behind her back too btw? It's not obvious with how the shading's still more on one side, and you don't really see them going behind her back - just getting cut off - but that wasn't anything I noticed right away right. Maybe a way of saving in on work; making things simpler? ;) Good stuff though.
