Cute and original.
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!
