Good choice of images and good job on the coloring. Only the blending needs some work. The lower edges of the girl are too soft. I think they need to be sharper and needs a little shadow (just a very thin line). There is a lot of empty space above the girl; it would look better if you placed the girl more to the side of the image, crop a large part from the top, and moved the moon to the open space.
But overall it's a nice image

I think I'd prefer the roses to be more prominent in the picture - but I love the scene that you've created. Well done
