SpiritDreamer: Thank you
I added a bit of shading on the dome and made the cranium slightly bigger, also worked a bit more on it.
Rebeccak: Thanks
Actually, I have no professional training behind me, except for two classes in Figure Drawing I took in two different (and too long apart) semesters in high school. Other than that, I am completely self taught. I’m 22 years old, and I started fiddling with Photoshop around 7 years ago, and then I also got into other programs such as Illustrator and Flash.
I am an avid fan of animation so it started from there. My drawings mostly consist of animation art/cartoony art, and now I really want to get to the basics to better myself. I sketch a lot, and love doing traditional stuff, but mostly work in the digital environment. I’ve never managed to get used to sketching straight into the computer with the Wacom though, that is something I want to be able to grasp as well.
I work full time in marketing, mainly as a graphic designer, doing commercials, graphics, brochures, website maintenance etc. And on the side I work as a freelance artist, mainly in doing character design among other things for companies over here 
I tinkered with the skull a bit, looking at my reference again. Put some shading on the dome and enlarged the cranium ever so slightly. I also fixed the jaw a bit because I felt it was a bit thin in the last version 

And I went to this little workshop in the beginning of this year that spanned 6 weeks. I had never done that before. We were mostly learning color theory, but I also got to do a sheep skull. I wasn’t too happy about the horns, but considering I had never done this before I thought it came out alright.
Done with pencil and chalk (taken with my camera phone, so sorry about the lack of quality)
