Breaking Rules

I was at work the other day and had an itch to do a drawing. On my break I drew this- an astronaut vampire fighting a zombie barbarian. I want to make a note of this- I completely broke alot of the rules I've set up for my work with this. Cross-hatching everywhere. No reference. An axe instead of a club for a barbarian. It was completely for fun- and a great way to experiment with media. I was happily surprised with the result, and decided to post it here.

Let me know what you think! Successful experiment? I'm excited to draw another.
