Glitch has never been my favorite thing, but I like what you've made here. It's definitely smooth, and I like the instrument choices. The transitions are all quite good, honestly. They function well in the context of this piece. I liked the drums when they were grooving. They really glued a lot of the sections together. In fact, I was a bit sad when they dropped out at 2:37 and didn't come back following that. It may just be a personal thing, but I was expecting a climax to kick in after that last chord. It felt like it was building up to something, dropped out, and... stopped. I was craving something savory to follow up on it :c But I dunno, that may just be me. Like I said, I'm not quite knowledgeable on the genre.
Mix-wise, I think it's pretty nice. I can't hear anything wrong with it, and there's some fun panning stuff happening here and there. It all meshes quite nicely.
Really good stuff!
