A friend of mine was asking me how I do the deeper gouges and scratches on my stylized sculpts, you can see it on a lot of my more recent stuff for the AWOK. So I threw together a little mini-tutorial for it using a claw from the Cold Blooded Weapon Set, I hope it can be some use to you, or let me know how you do it, always like to learn new things.
It's free, so if you like it please consider checking out my actual work and giving it a like or comment. :)
