Nice! Simple but very enjoyable. Love how bouncy it is.
The first part not much to say but good to have the reference material for what follows; I did appreciate the soundfont though, had the right kind of bounce to it.
The second part was cool, I wanted to love it but I did feel it was quite repetitive vamping over the same chord pretty much. I wanted it to reharmonise (which I was rewarded with later). But a cool sound nonetheless.
Part 3 was my least favourite. Not bad, I just didn't love it. The ending was a bit jarring, though I realise it really is supposed to flow seamlessly into part 4 (I would have stitched them as one complete track for the stream).
Part 4 despite sounding like your least favourite was actually the best part for me. A culmination of all the ideas you had played with this far and a fun listen. My head was boppin 😄 And I really liked the variation in voicing and reharm (I think it was anyway? It sounded great in any case).
Solid effort. I also went with Bach for my submission, taking more of an "inspired by approach" than a strict rearrangement. I love how Bach sounds in different styles, truly one of the masters that I aim to learn from 🙂
