The pineapple seems sort of realistic, style wise, and the hedgehog's face/legs do too.. So I can't really tell what style you're aiming for, as;
The spikes look like they come straight off sonic , which looks.. Comparatively wrong. A hedgehog's form is really just ballish, or like a rat/mouse/guinneapig - The spikes would look like coarse hair, and not actually deform it's shape.
The spikes you've done facing us look nicer, it's just the ones on top that're making it jarring (to me at least)
It is v cute though, I love hedgehogs. Not convinced they eat pineapples though.
