...i'm agreeing with merlin about the apparent dissary of the objects...if you gave them some sense of purpose i think you'd have something...i thing the composition is a lot more promissing than the any of the originals...
...here's what i'd look into doing if this were my image to finish...blood on the blade of that knife...maybe a few drops on the table where its stuck into it and a little pooling at the bottom...some liquid pooling from the spilled goblet...and a killer texture on that back wall to give it the dark damp basement or dungeon or catcacomb look...maybe some chains if you decide to go the way of dungeon...
...anyway good luck with it and i hope you get 'er finished up...we're almost out of time!
