Like the title says, this is just a rough concept for that one character from my one story, Teenage Pet. This is Derek Bradman, the antagonist, who's mutated into this abomination. I know his one arm looks like it's in the wrong place, but like I said it's a rough concept, plus he's supposed to look pretty deformed and grotesque-looking.

I'm actually surprised this turned out pretty well for a quick lineart concept too But there are some fixes I would have to do if I plan on doing a non-rough concept in the future. Basically the only thing I would have to fix is how currently bulky his arm is there. It's supposed to be more bulky than that. I would've taken the time to fix it, but this is rough, so it doesn't really have to be perfect
