I suggest, first of all, that you save up tc to get a 512 head texture like...asap. That way you can start making high Q heads that people (including yourself) can see ingame and out.

Now, maybe you are going simplistic, but you still need to be creative. For your first textures ever, it's good that you play around and get a good understanding of the mapping and junk.
However, never settle. Look at other peeps art, online or in forums.
Try to roughdraft and come up w/ ideas outside of the computer screen. Feel free to doodle here and there and just get that creative juice flowin'.

Honestly, you are doing super fine so far, being as new as yourself.
I started just like you man!
You will develop your own style as you go, and use your mistakes to polish your future works. (I haven't uploaded finished piece but whatever...)
Keep at it and good luck!
