I love the simplicity in this one! Very imaginative and well composed. Colors are great also! BTW, you could touch it up a little bit to remove that one "dangling" thread (top center) from the cloud :)
I've tried "kill" the dangling one, but my photoshop experties can't beat that yet, the thin line crosses diferents "whites".
But, thanks for that kind of critic, that's what i'm looking for, true and honest. I'm already pleased to joined this community.
