More skulls as promised

Some of my original sketches that inspired the previous post. It was a small challenge that Liam gave me. Draw a bunch of different types of skulls. Can you tell which ones I was able to do?

A sneak preview:

Of my next painting. Still in the design stage. Did some research online to get this done properly. Now thinking on it though, the canvases I just bought might be too small...
We'll see how it is after final design and layout. Just making sure you guys know I'm still around. I'll give you another page of skulls tomorrow.
Enjoy!
