ok composition, the way the circle was done on the left looks a little familiar.
Place the cirle better, maybe make it a little smaller and rotate it, and also maybe do it more times, kind of like bits and pieces of the girl are being blown away to create better flow. oh, and get rid of the guy on the right, its throwing the whole sig off, just doesnt look right.
also, experiment with the pen tool, use a light colour.

i think it would be cool if you removed the circle thing on the left.
