It dont mean anything if I enjoy something or not. What you do is OK, as far it realizes what you intended to do.
It is just a kind of my personal impression that the wonderful world of innocent child-fantasy like we feel being akin to the world of Fary Tales (also the world of Shakespears Midsummernights dream, Lewis Carols Alice in Wonderland, Frank Baum's Wonderful Wizard of Oz) is something quite different to the world of Halloween, scary things, super heros etc. which is characterized by emotional superlatives and do not have that background of as I said unbroken innocent harmony and play. Both are undenyable things which can be reflected in music but imho not both at the same time, since. As I said do not take my objection to serious, it is just my spontaneous impression of something I feel being a bit inapt. I personally would if I would do something in music like that either do one thing or the other. For me it is just cleraly something very different especially when I think of its musical realisation. But this just my personal view.
