This is gonna sound noob-like, but arrangement/interpretation is just really hard for me lately.
When I first tried my hand at mixing, I didn't have many options for sounds, and I just used what free stuff on the internet that I could actually figure out how to use. That stuff is better than what I do now.
Arrangement is hard for me anyway, though. I see a good track and think how good it is. I sometimes feel like I shouldn't screw it up by changing it, even though that's pretty much the goal of remixing (not screwing it up, but arranging and interpreting).
I feel like when those first chords come in, the synth there really fits. Like a lot. Other than that, they're really just generic and plain. Barely any effects at all.
The drums are just ACID drumloops that came with FL. It's the same sample over and over again, unfortunately. Drums are not my strong point. Anyway, this drumloop seemed to fit the best, and once I heard it I didn't really want to change it.
So, tl;dr: I'm not good at arrangement, my drum samples are rudimentary, and my synths are plain.
