Hey, Daniel! Thanks for the feedback! Truth be told, I've been making these my first scoring something on MuseScore and then editing them in Audacity (really most of the time just reversing them and playing around), and so I don't have a good understanding of how the final product is going to sound. (That is, for example, you mention the abrupt stop in the beginning. Well, in the original score, it made more sense to introduce a short stop in there. But here, as you noted, it doesn't.)
I'm planning on getting an actual DAW (technically Audacity is a DAW, I guess.) I already installed (basic) FL Studio but, by God, I haven't the slightest idea what to do hehe. (The UI is quite intimidating. How do I make a synth again?)
About "timbral richness," what do you mean by that? I feel like my lack of knowledge is showing hehe
