i think it should be like a dark bar or noghtclub kind of coloring...like purplish-blackish-skin-tonish lol and some pink shine like theres neon lights or something.

warm colors? brownish-red, browns, dark shades of yellow.
the faces arevery emotive and well done! very stylish as well.
i agree with joe on the hand, very precise. i like his eyes also.

Super styley, as your work always is.

My two cents:
I like it the way it is, but I'd have to ask what kind of feeling are you trying to portray...any message in particular. (Color theory might help with that)

I do not smoke, but being this is a sequence, it is possible that maybe you feel different during the process of smoking...a buzz to a chilled feeling? Maybe the colors could corrolate...several different colors to go with each stage.
Perhaps a sort of greenish/brown color to a more excited red brown and then to a bluer brown?
I'd say alot of it has to do with you personally, because the my personal feelings toward smoking gives it a very different tint.
Yeah that was about 4 cents.

warm? pft. when I look at this I see green purple orange and hm.. yellow. this is awesome <3

red white & blue

Hey pockster, last time I checked orange and yellow were warm colors, ya dumbass. I like LisaAnne's idea. My idea is that you let me color it. :D Otherwise this is a great sketch black and white. I am jealous as hell of that hand, and the eyes of Mr. Exhale.

brown hats

He was orange and yellow but started smokin those awful generic butts,, now he's green

Another one to covet.

This is way too cool.

Uh huh. Twat ever. :} I still like it.

This freakin' rocks my socks off until next thrusday when I find them out in the lawn. Alone this was a great piece but it's even better with color.

Yea! I like the colors...it looks like you took alot of the ideas and put them together, and BAM...kick ass ness.
Haha my wonderful vocabulary. Seriously very good work.

Top notch stuff, Alex! I might have mentioned this before, but I really like your artwork! Keep it coming! :)

i like his blank expression...that creepy disconnected look you see in the eyes of a a true addict.

Hella stylish..Love those facial expressions..
