Base was me looking in the mirror snarling at myself. Then I removed an eye. Judged about how that should be by feeling around my eye socket. XP I also took my shirt half off for reference for how the rippedness would hang.
After the sketch, I scanned it, and spent the whole day working on it in photoshop.
Ik, it probably SHOULDN'T take me a whole day to finish something like this. But whatever. I work slow I guess.
