Looks neat so far.
I would try to shade/section parts of the cherry tree more so that the colour doesn't looo as flat. If you look at a tree, it has a LOT of gaps between the leaves, so maybe leave it a little more spaced out, or add definition into certain parts. Even just make a section brighter/darker and add shading around to make it stand out. I love the spots you used for the blossom parts, it's super cute and adds to the style!
Also, maybe add a lil moss or something on the roots, just to make it look the part!
