Mail Snatchers & Killer Dogs

I did these quick sketches a few weeks ago. Yeah, I still need to finish them (ink them, etc).

The Mail Snatcher. He takes your mail right after
it's delivered. He knows things about you. Yeah,
he's that person.

Killer. Not him, the dog. Don't let appearances
fool you. See the missing arm? Yep, all dog.

I'll put these in my Etsy Shop once i've finished them. 10% of each item sold will be donated to Joy 2 The World.  I'm still taking on one or two more commissioned pieces for the holidays if anyone else is interested.

For these pics I got my inspiration from the mailman (first pic) and from my friends dog (for the second). I like adding twists to them. Where do you usually find your inspiration? Does it just come to you or do you go looking for it?
