I'd love to be one of those convention-hopping webcomic artists, since the idea of being able to write/draw my own product completely by myself is really appealing, but I'm aware that isn't exactly the most lucrative business. I'll probably end up in illustration, but I think concept art would be my preferred job outside of webcomics.
I can't draw, but if I could it'd be for doing some web comics, nothing really official that anyone would put me on their payroll for; er, there might be webcomics on a payroll, i don't know, but it'd mostly be just for creative purposes or something? I'm not really sure what I'm saying.
I voted Illustrations, but only because I'm better at them right now! I definitely want to get into concept art and character design though. My goal is to sort of combine all of those together into a super-art-field! But really, I think that they all fit really well together and you kinda need them for each other. It's so fun!
