FINALLY!!!
Yep, that's the first word that comes to mind. I've been working on this thing on and off since June - mostly off, as in not touching the picture for weeks on end.
All in all, I can say it was quite fun... Although there are some obvious mistakes, such as the perspective and how both the background, foreground, and fore-foreground seem to be in focus. I'm no longer sure where the light source is, too...
As a BIG surprise, Garrett on the rooftops, suddenly realising he's in trouble and better clear out fast. Big surprise right? I mean, who'd expect
me to draw Garrett, right?
The only thing I can say is 'enjoy' and 'whew, I finally finished this'. Cya.

...
Wait... Where did he go??
This is astounding! I do envy people that can digitally airbrush so well!
