Why don't we have heated toilet seats?

Here is a couple new things, the Hellboy is a sketch for my buddy, comic writer and Dabel Bros. guru, Derek Ruiz, he had an apartment fire a few months back and lost everything, including his comic collection which numbered close to 30,000 if I remember correctly, so this is part of a "care package" I'm sending off. The other sketch is for my Actionopolis project, I'm still trying to nail down the kids' looks, they are supposed to be around 12. My publisher is happy with this except for the 2 girls, who I still need to tweak.
