Here's my somewhat less awkward bio picture. I always seem to have trouble with how big/what resolution file I should start with in order to make a crisp final product without it getting all pixely. 

I made it round since most profile pics get cropped into a circle nowadays and I wanted it to show up well without someone having to click on it. I'll probably tweak it and make it better, but this was a first attempt that I'm somewhat pleased with.
