Very nice. I give it 4 stars. The missing star is primarily due to personal preference that the cursors would have a bit less contrast in the beveling. They are quite dark in some spots and quote light in others.
However, you hit several other items that make this set deserving of a good rating:
1. You have all 15 cursor roles.
2. The set has a consistent theme throughout. All are clearly part of the same set.
3. The cursor animation does not detract from functionality. is smooth, and is not done in such a manner as to be annoying.
4. All of the resize cursors are the same size (In some of my own early sets, I made the diagonal cursors larger because there was more room on the drawing canvas going diagonally. I no longer do this since it makes them larger than the horizontal and vertical resize cursors and I feel that it's not consistent.).
Great work! 
:-D
