I kinda have a hard time to tell what you intendet to show with this picture. A bloody cat(-bug?) with some dead dude having his face torn off... hmm?
I think somene has to know bravest warriors to understand, right? No? Oh well...
The picture is lacking depth. Everything looks like it's on the same plain, especialy the bookshelf.
I suggest trying to paint pictures with far reaching environments (like a mountainship or even the inside of a storagehouse) to get a better grasp on depth and perspective.
Apart from that, the cat looks quiet intimidating and the stylised skull of the dead dude looks pretty good. Neat, maybe flawed, small illustration.
