Do You Think We Could Have Been Friends?

I did this a while ago on a bumpy flight to Seattle (what fun that was, I felt like I was going to be sick half the time!). It's from the Blue Spirit episode ,which contains most of my favorite Zuko and Aang moments (I don't mean romantically).
Also, I have "issues" with my eraser, so I tried to brighten the background with photo shop, which I'm not so skilled with. It worked (sorta), but I'm afraid it made the picture grainy. Please except my sincerest apologies, I promise my eraser and I will be spending some quality time together over the summer! Any attempt at mustering the harshest criticism you can think of would be much appreciated!!! : )
