Its gorgeous. Plain and simple. The composition with the tree is strong, I like the way how the tree makes the eyes follow the path in a zigzag pattern. The brightness of the red helps bring out the composition even more. More so when the red flowers bunches at certain points on the tree. Also the tree has some good texture.
I do think the background needs a little work. Some of the darker strokes could have hinted that it was clouds, but the consistency was trifled a bit by the round stokes near the moon in the same shade. Maybe if those strokes were a little bit lighter, I could have made that out as light? And this is minor, but I think that more of the flowers need a little texture as well to bring out the softness. I see some out of a few but the rest is a little bit flat.
I still think its gorgeous. It goes into my favorites.
