Persephone and Hades character design Picture

I think the title explains it. My first doodles of these guys, where I was trying to figure out what they looked like. I took some of it from my imagination, and some from this website called theoi.org, which my English teacher reccomended last year as an accurate mythology website.

EDIT: Sorry that it's a little blurry.... if anyone wants me to scan a certain picture for better quality, I can ask my friends to scan it for me or maybe at school or something, but I just don't have a scanner at home...
