Boo!

Hey! I'm just getting into "proper" icon making... And I just made these (in the spirit on PoA*15 days!*) And I'm wondering what I could do to improve it! Any suggestions are welcome.. I just want to practice so I can improve! I'm rather partial to the one without the text.. It's just cleaner looking..! Please be gentle.. I worked for a good bit on this one... (stupid transparent lines took so long!.... ;D)! Thanks Loads! -Kate
