I believe that your piece could use better AA, especially the boss guy. I'm assuming you attempted to give it a cartoonish style, using wide strokes for details, but they look jaggy and unrefined.

I have difficulties reading the lady's silhouette.
There seems to be plenty of AA, especially around the outlines, which can go with little to no consequence.
I like the idea and the background!

I keep seeing that necklace as the fox guys teeth, now it can't be unseen. Sorry I have never done any ismotrec work so I can't give advice but perhaps you could make a post on the wip forum and get help there.
