i rather like the variety of drum riffs! and i think the melodic progression is dark and high-energy enough to fit theme. i personally think it just needs a little stronger bass/harmonizing sounds (but maybe that's just personal preference, haha), but overall i think this was very well done, despite your misgivings about trying out a different genre. great job! :)

Love the high energy of this tune! As others have noted, the drums could be more structured. Or you could probably achieve structure through a solid bass guitar/synth part (and keep the drums as is because they really bring the intensity)

Perhaps you could experiment with accompaniment parts (strings, upbeat chords, saw wave) to complement the melody.

Either way, thanks for sharing this catchy tune!

I think your melody and harmony was really solid, well done! I think you could improve most in the drum department, a little less chaotic and a bit more steady (even though I loved some of the chaotic elements) would go a long way here. Also, some of the drum hits were not properly timed/quantized or accidentally "left over", which took me out of it sometimes.

I think Blue Lava has made some excellent points regarding instrumentation options. You can get a good understanding of what people conceive as Halloween-y by listening to the other entries and especially reading the comments.

I think this is very well-done, especially for having it be your first attempt at this. The melody is very well-written and is my favorite part of this track. The most Halloween-y part is the natural 7th scale degree as the penultimate note of your melody, I love it! I think as far as composition goes, you have an awesome song here, a suggestion that I have to maybe make it feel more like a boss battle theme is to add some energy with alternate instrument choices. The piano, harpsichord, and bells sound very sweet, which is maybe why your ears don’t hear it as a boss theme. Without changing the music at all, if I were approaching this piece to turn it into a high-energy song, I would take the piano left hand and put it in some sort of electric bass or bass synthesizer to give it a little more oomph. I would probably substitute the piano for a harpsichord, or a different type of piano with a less “clean” sound. Then substitute the harpsichord-doubled melody with a high synthesizer or a theremin sound. If you take the chords of the piece and put them in an organ as a pad instrument and then add more crash cymbals, I think that would transform this piece into what you are envisioning! That’s just my approach, there are many ways to do it though! Great work and thank you for sharing!

This sounds great! I really love how the accompaniment works together with the melody to form a very coherent kinda theme. I know that sounds a bit generic, but I think this song is really good at telling a short story. I'd say your attempt was successful!

I might be crazy,  but the melody reminds me a little of the melody from the Gravity Falls theme. The chord progression is also really nice. Great work!
