Thanks for the in-depth feedback :D
I've barely ever really utilized panning before, so it's a great suggestion of something I can try next time! I like that idea.
I've never used "side-chaining" (nor know what it is), but I'll look it up. I myself felt like the kicks were quite punchy and on-the-beat already, so I am a bit confused about what effect side-chaining will have. Could you elaborate?
