I don't feel like there's any flow. I didn't know Al was in there at first, either. Maybe the sharp tool could be used on him and the blur tool in some other spots. Finally, add some lighting; it'll bring Al out more. It's pretty decent, though. The effects are nice, and some of the blending is, too.
Thanks Y.M. and Casta, i will take them into mind and try improve it with lighting and shaperen the render etc...
