My favourite is definitely the second one. I'm missing the D'nB as it's way more fast-paced. Also, if you could've stayed on the path you were going for a while, I think you could've made quite a great song. Not saying that it's bad! It's clearly pretty good! Way better than I could compose, but I prefer D'nB and would really like it if you stuck to D'nB. Then again, I'm not the one who decides whether you stick to the older genres or not, as you decide whether or not you change. All in all, there was a very good halloween feel to this, compared to the second one. The laugh was a total killer and could be pretty scary if it was played under the right element. I'd say that for a halloween song it's actually really good. Whether or not I like the genre is a totally personal thing, so the score will not get lowered because of that. Sounds REALLY solid.
Have a nice day, pal. Keep it up.
