I am looking for a good tutorial on making muscle veins on skin with photoshop.

Any help would be appreciated.

After a quick google search, I came up with this set of brushes:

It's the only useful thing I found. There aren't a lot of tutorials on this topic

I found a great photoshop painting tutorial:

Shows you how to paint veins over muscles as well as how to paint freckles and skin, very cool.
