Hey Nick,
I listened twice to samples of your album, getting my ears a few hours of rest in between.
Some of your songs sound very bright to me. A bit ear fatiguing, in fact. Around 17:40 for example, I think the (supersaw like) synth sounds too bright for my ears. 36:37 is another of those moments.
Nothing dramatic, making a gentle roll off on the high end of the synths would fix the problem. I think those mixes will have a fuller, more bass heavy sound but lowering the high frequencies. It's not in all your songs, though.
I like the genre and the musicalty overall. I would download an album like this.
I hope others hop in on this topic and let us know what they think about the mixing.
