It looks fantastic, but not yet real.
It exists in a world of it’s own. If you want to make it photorealistic, make a model of the dark corner of your kitchen in which it will lurk and render it there. It also needs some real-world reflection. Have a look at some of the HDRI mapping stuff around for the reflections in the copper wires and the steel spring.
it originally was just the model, no scenery or anything, and when i finally finished, during post work, i thought it would be a neat idea to put the mouse, so i wasn’t really thinking about putting cheese during the modeling process
It’s not photo-real, but I still like the style. I’m not sure why you included quite so much empty space on the left side of the mouse-trap. I’ve just noticed the blurred mouse! at the moment the background is so clinical it looks like a lab-experiment of some sort… The sading on that trigger thing (the part that looks like a bit of tape) is a bit odd, but I’ve not seen the actual trap, so I don’t really know.
