I know many people kind of scoff at the idea of drawing people from photos, but I tend to just laugh at them. I DO WHAT I WANT. Anyway, here are some portraits I've done in the past, and I'll be honest, they aren't all that wonderful or whatever- but I still like them.
Loki from the Avengers, done in watercolour pencils
Loki again, just in pencil
The 11th Doctor
The 11th Doctor again, because stetsons are cool
And Hope Estheim, from Final Fantasy XIII-2
