This is an illustration I've been working on in my spare time. It's not for anything specific, just playing around with different techniques in Adobe Illustrator. If you look closely at the iris of the eye, you can see the various radial patterns I used to create the texture. Most of these patterns came from the GoMedia Vector Packs that I have. The scales are were created from a stock shield vector and the eyebrow uses a number of different flame vectors. Again, I was playing around with various techniques and this has been created entirely in Illustrator (except for converting to a bit-map to display here).

The image to the left is a detail of the eye itself, you can see a full version by clicking "Read More" at the bottom.
