Good job! Not bad! ;D
I have a a few suggestions, though.
The coloring is very sloppy. If you're really going to use the mouse (which you shouldn't be in the first place), you should at least try to use the fill in tool or something of that effect.
Also, try to pay even MORE attention. For example, many things are noticeably very misplaced, and many lines are sloppily drawn and don't appear as though full effort was put into them.
But, really, you did pretty great!! :D
Anyways...
Alrighty, let's see if you managed to retain anything that you learned from copying that image. (assuming that you were paying attention to every detail)
Draw an original picture, and try to apply what you just learned. And, PLEASE, use pencil. Do you have a way of scanning it in and posting it here?
