The Magnolia Crossword #1: Names, Groups, Groups of Names, and Names of Groups

First of all, I do apologize for the blurry quality, the crossword only exists in PDF format, and it's hard enough to convert it into a PNG. But here is my first-ever crossword I have ever made. The theme of course, is "Names, Groups, Groups of Names, and Names of Groups", which, to be honest, came into mind after the whole crossword was finished. Hopefully this one isn't too hard.
