Ooo! I really like this one~ :D
Her yellow eye really complements the sunlight peeking through the room. The lights and darks are really good!
The main colors, like her purple hair with her shining yellow eye are beautiful together.
If I had to critique something I think her hand/arm reaching out needs more perspective and dimension added to it. Pull the hand a bit away from her silhouette. A good silhouette is everything! ^^
