Nice work
Just got the demo for Ps CS5 yesterday actually.
Portal 2 is a great game, I thoroughly enjoyed it, so I enjoyed seeing artwork made of it. I do have one suggestion though: the part of P-Body that's still on the other side of the portal should have some of the orange reflected on him, since the other portal would be orange. I think you've done a amazing job here. Keep it up.
If only I had my slow clap processor.
