Cool capture. It's artsy and I like it.
Given your intent with this photo - that it will be one of many presented en mass to draw viewers in and motivate them visually to look and linger - I think it's a keeper. As a stand alone image I'm aware of two potential issues:
1. The straight-on view creates excessive foreshortening of the facial features which is further exagerated by the close crop. If the cat has a bit of a flat face to start with...
2. It's definitely 'scary' in that humans are hard-wired to pick out of the background that triangular 'predator' symbol formed by the vertical nasal cleft and the two lines separating the upper and lower mandibles that move down and to the sides from the bottom of the nasal cleft. That figure has been adopted and turned into a danger symbol used internationally to warn of the presence of radioactivity.
I don't think 'scary' is bad per se, but there is no denying that upon registering that figure in the brain's visual cortex, some people feel the urge to move on as opposed to linger - and it often happens unconsciously. Choosing when to emphasize versus de-emphasize that feature in images of certain opportunistic predator animals allows the photographer more influence in how the image is experienced by a viewer.
I'm certain I wouldn't have thought about this in relation to the image above if folks hadn't used the word 'scary' to describe it. What's so scary? That little kitty? Those little teeth? Those big eyes? No way. What's scary is the archetypal fear triggered by picking out that simple shape from a complex backdrop - the prospect of a big cat, invisible against the background, watching you... waiting for you to betray your vulnerability... attacking you with sudden overwhelming mortal force... before you can even blink! That's what's scary.
All of that stuff aside, I wouldn't change the picture unless it's intended use changed.
