So.
We all know that basically, drawing portraits of anime characters and occasionally a good photo is all I can really do with art. I suck, I know.
So. I have an idea of how to combine these into one (possibly) grand idea.

What I wanna do, is get a larger surface than the 8 1/2 X 11 I usually use, maybe a poster board. I'm gonna but just the facial portraits on the board. A bunch of them. Like, my Yoruichi, my Serena (not up here), Deidara (currently in progress), etc. All my favourites, intercepting eachother all over, except for in the center. There, I wanna splice a picture of myself, possibly in my General Cross cosplay from this year's AB.

The reason I'm sharing this idea with you, is because I want to be able to share the final product with you. That's why I need your help. Since I want to use a larger surface like a poster board, I have NO freakin' clue on how I'm going to get into my computer. I mean, I can't scan that. And if I took a photo of it, I just have a feeling the lines and details wouldn't come across very well.

Any suggestions on how to get it onto my comp or at least take a decent picture of it?
