Cute, original but these cursors are just pointers.
I would suggest that you consider designating proper cursor roles to these cursors and expanding this set. If you do let me know so I may review this set again.

You can find information on cursor roles here: http://www.rw-designer.com/mouse-cursor

To illustrate why cursor roles need to be designated you may want to check out this tool many use which requires a more complete set of cursors with defined cursor roles: http://www.rw-designer.com/change-cursor

Keep up the good work and make more cursors!
