Caverns of Time, a self written and drawn comic for an OCT (Original Character Tournament) held on DeviantART in 2011.
The idea of such a tournament is that you enter with an original character you created on your own, and battle against your opponent through the use of a comic. A selected jury decides which of the comics of the competing contestants wins and goes through to the next round. Each round you are competing against different contestants until two are left to fight in a final battle.
I got through to Round 2 but then dropped out due to lack of time.
