That melody is catchy. I'm tapping along unconsciously. I think despite the poor quality of instruments, this song manages to stand on the merit of its melodic writing.
also is that M-Theory?!!! <3 memories
What I would do in the absence of better instruments is make the best mixing and FX choices you possibly can. Meaning use reverb sparingly, and when you do use it, clean those low mid frequencies -- and by that I mean eliminate them. Make use of transition wooshes, find some cinematic cymbals, or make your own reverse cymbals for transitions. Find some good free instruments such as Junk Guitar for sforzando, a free amp that's half decent, and as many nice free drum samples as you can get. I have tons of them in my news posts if you can be bothered to sift through them and some FX no longer available on the web if you'd like to PM me some time.
Despite being a relatively simple piece and being severely limited by lower quality instruments like FL slayer which I think I hear, I really enjoyed the piece. Your writing is a huge strongpoint here. Looking forward to hearing from you as you expand your horizons over time.
Thanks for coming out to NGUAC!
