I appreciate every kind of constructive criticism/feedback. Some things were mentioned much more than others, so I will try to clearify them for once.
"Your music could use a bit of better mixing." or "Try to normalize the sound so it sounds more rounded and louder."
I totally agree. The reason why I am unable to give my compositions much better mixing is simply stated: I lack the equipment and cannot afford it. I really can't and I hate that. My setup was - and still is - extremely provisional and I am happy that I am able to record my ideas in the first place.
I normalize all (!) my compositions. I have sensitive ears, though, and cannot stand it when my music is too loud, especially the high notes or the bass - it actually hurts. So sorry, no changes in this regard from my side.
"I'd suggest not to use a fade out to end your composition."
Generally I would agree, but there are enough other better-known artists out there who do the same and nobody complains about it. My main inspiration for composing, ZUN, composes a lot of looped pieces for his games. If I was feeling particularly ironic/cynical, I could start uploading extended 15-minute-versions of my compositions instead. Nobody would want that. I try to end some compositions "properly", but it always feels off to me. So please, don't suggest this to me over and over.
"The drums in your pieces could have been a little stronger in the mix."
Again, this is due to my crappy equipment which makes it nigh impossible for me to balance those things. I try my best, but I am not willing to adjust thousands of drumset notes individually.
"There is too much going on at the same time."
This usually appeared on my older, re-made compositions. I am working on this and will try that future compositions won't sound as crowded in the instrument section.
If there is anything else you guys want to let me know, I'm glad to take in feedback I can use at any time. I just needed to vent about this a little.
