Wow, I love the shape of her face and her lips. The lighting you used really gives sharp detail to her jawline and the shape of her face. Even the slope of her shoulders is well defined. Fantastic lighting there.
Lol, sounds like you wore yourself out. I know how that is though. Ask anyone who's gone to a convention and they can tell you about pushing your body past its limit. My first anime convention, I was running on put excitement and joy. I don't think I ate more than a couple handfuls of cereal every day that weekend. My most recent con was worse because we were running on no sleep. We stayed out late to the raves and then got up early for convention fun. I think we had about two hours of sleep before we had to leave the next day for a three hour drive home. Plus I wore heels for most of the weekend. The pain we go through to enjoy our hobbies.
It's funny because we never drink or do drugs at cons (mainly because most of the group consists of minors), but we always end up in line next to someone who's drunk when we're waiting to get into the rave. The first time the guy was a complete ass, and the second time the whole group was awesome. I'm excited to see what kind of drunks we get next year.
