1. The tracks have an ok mix, they're a tad muddy, and some denoising for the mix would help. I don't know if it's an issue with your recording software or what you use to record, but it's very low quality, and there's some weird low end that pops out that drowns the mix with too many clicks (in track 1). I would refrain from using too many O or K commands unless you're masking them with percussion or something that requires punch, they can really overpower stuff if you don't EQ properly.
2. Honestly, I dig the melodies a lot even if they're "cheesy." I'd be lying if I said they weren't a bit catchy. Though 8 minute songs are a bit offputting, and it does get a tad repetitive. There are a few accidentals you have to watch out for, as they sound a tad out of place and bring you out of the mood when you hear a bad note.
3. Instrumentation needs work. Leads and arps are pretty good, though they could use some more PWM. Samples are done tastefully.
Overall, keep up the good work.
