sounds fun. most of my art is concept sketches for several novel projects im working on. I used to love drawing comics.. i still do community ones (improv comics where artists battle it out by taking turns doing pages) one one of the forums i frequent I accidently started one with this sort comic (it probably doesn't make much sense if you don't know the character. im too lazy to really explain, but she is an OC of mine, who doesn't have much sense, and changes into different personas depending on the stimulus.
one artist thought it would be fun to "join in" and replied to it.. and it sort of continued.. with more and more artists taking part. the story arc is pretty simplistic but fun.
.. its a lot of fun, and you learn a lot art wise, because your pushed to draw situations and characters you would otherwise avoid.
Anyway i would love to see your cover art. <3 i love seeing what other people are doing with their projects.
