Thanks for the comments. It's an Eastern Redbud (at least according to the sign by the tree), and the buds were actually coming off the main part of the trunk - this was the largest cluster, much lower than where the tree started branching and had most of its flowers and leaves.
I agree that the highlights on the flowers are a problem - hadn't thought about it in terms of overall overexposure but that definitely makes sense looking at it now. I also see the focus issues. I'll have to look back through some of the other pictures I took of it to see if they work better in those areas.
A nice shot, unfortunately there seems to be too much light on the pink buds which causes a loss of detail. I like the diagonal lines of the tree trunk and the out of focus background.
Subject is overexposed. Recomend shooting quicker or a smaller apature. Since this was advanced editing you could have shot so that none of the subject was over exposued and used a slight dodge to brighten up the other side of the branch.
