Art Review:
The coloring for Doug N Exile is simple, yet effectively shows us the detail in the characters and the backgrounds, which makes it all the more disappointing when the color disappears later on. Compare this page:

with the subtleties emphasized by the coloring, to this page:

where everything blends together. All in all, the comic should really bring color back to make it feel like we're in the world, instead of staring at drawings.
Writing Review:
The writing more than makes up for the art. I'm loving the character of Exile and his sociopathic tendencies, which sometimes seems highly justified considering the people around him that are total jerks (like the one kid at the baseball game). The only problem I have with it is there is a long period between updates, which throws off the pacing a little, but this sort of thing can be improved over time.
Overall:
I'd rate this comic a 7/10. The art really needs the color otherwise it comes out flat and boring, but the humor of the characters more than makes up for it, despite the comic's pacing. All in all, it's a recommendation, but it does need some improvements.
