Hi Julia
Whilst I like the idea I am not a fan of the logo, that needs some work also as the logo has green in it I would of expected the design to follow some of those colors not just blue and white...
Have a look at the notes...
I hope my points help, good luck!

there's nothing special about it, it could be a lot more fun and funky...
this is bad english, it should read "get feedback"
where is it? make a prominent hover color I would suggest the green from the logo
I know this is for the ipad, but you still need a hover color for this too
2Aaran Casey: thanx for your comments!
