I've been doing rather a lot of portrait practise the last few months, and as you can probably see, still lots to learn. But I feel I'm getting a little better as I go.
I challenged myself to try a person people would be able to recognise, and since when I started this, I'd been listening to the Dr. Horrible's Sing-Along Blog's soundtrack waaay too much, Doctor Horrible it was. (Those songs are so ridiculously catchy~)
