They are well done. Animations are smooth and not distracting. The cursors are not gaudy or poorly drawn.
However, I leave off a star because the animation for "MetaBlue busy" does not match your theme as well. All of the other cursors are pulsing with lights and this one instead has a radar sweep-type animation within it.
My suggestion is to change the "Normal" cursor you have to a static (no animation) cursor, and instead use the existing "normal" cursor as your busy cursor.
Alternatively, another idea is to make a cursor similar to normal, but with an extra fast pulse and that would then become your busy cursor.
