I believe he meant it to be like The Graveyard Krypt in Deception, hence the Coins. It makes sense since, Monster's only appearance was in Deception.
Anyway its not too Bad. The Monster sprite isn't too bad, but I don't like the projectile he launches out to finish his opponent. Otherwise, I think its pretty cool.
aww you could have though of something better for Monster's fatality. a projectile? Yuck. Anyways its not that good, you can barely tell what Monster looks like, the animation is too slow, and not to mention that if you're gonna dim the entire background, dim the coins too so it won't stand out.
