Not bad, but could be a little better.
the tree is potted too high in the pot. It should be potted lower, with the surface roots more buried. "Exposing the Nebari" the surface roots should not be done early in a tree's development, it is a step for late stages of development, usually after 5 or 10 years of preparation root work. If it has only been a day or two, I'd repot again lower in the pot.
Second, the right most branch, you have wire on it, but have not bent the branch. If you are not bending a branch, you don't need to wire it. Put a little arc or curve into the right most branch, it will look better.
All in all "pretty okay" first effort, my comments are only to help.
