My style is heavily ‘manga-influenced’ so if you dont like that, I cant help you.
Heres some examples of some quick old things I did:
I can do full body shots with a background and fairly-detailed coloring.. like so:

Or plain headhots, with detailed coloring like so:

Or more pencily/sketchy style (more pencil-like than this one too):

Or pretty generic ‘anime-ish’ cell shading of several kinds:

I can do grayscale art too, if that fits your comic. Also your comic doesnt have to be manga-styled but my art wil be so keep that in mind. I do a variety of poses and will use photo-references when I need to.
I cant draw fanart if its a sprite comic or if you only have one page or two (I need to ‘feel’ the character).. also I cant draw furry/anthropomorphic characters, Im just horrible at that. Just a tail or fuzzy ears is okay, though. I also wont draw hardcore sexual art (yaoi, yuri etc). Romance is fine.
If you're open to me drawing you some art of one or multiple of your characters, go ahead and say so. Like I said Im also open to coloring your work (cell shaded anime look or more detailed). I only ask in return that you post the art on your comic page and let me post it on my own DD comic I'll be making to store all fan-art I'll do (plus a link to those comics). Also, you can make suggestions but in the end I'll decide what exactly I'll draw and how.. and again if you hate manga-influenced styles dont bother with me :)
Why exactly am I doing this? Cuz its fun, fan-art of popular stuff has been done a million times, I like variety so making my own comic is not an option either.
I'll be here.
