Just be willing to post an image of yourself online and you have a free drawing packed and ready to do stuff with.
Gimme a day or two for each of em, this takes time.
Also, if you have any specifications (for instance, if you want it done kinda cartoonish, or you want color somewhere) feel free to tell me.
I might get the first one done tonight and scanned by tomorrow.
UPDATES: Also, don't be surprised if I put in pics of my progress too. I'm a little bit of a slow worker and don't want you to think I am not doing your pic.
And I would really appreciate just faces, but anything is acceptable.
