I adore this peice. So simple, yet so advanced and impressive! Big up. I'll have to give it a 4.5 because I don't like the smoke. It looks like its just pasted on top of the image, and i think an artist with your talent could have put a lot more effort on creating a better smoke-effect.
But as myself, you maybe get a little lazy and just wanna post your work before it's just perfect. Anyway, awesome.
