Skull Tattoo Design- Upgrade

Finished this tattoo design today...It's something that I've been wanting to get on myself for years but have been waiting (a very long time, I may add) for the right time..Thankfully I did wait it out because the one I had drawn before looks like pure shit...

You can see that one here *cringe*--> [link]

Took about 10 hours...I was stalling most of the time.

tools: Derwent Graphic pencils & Sharpies.
