That's one unique intro. I'm not sure what's going on at 0:17 and beyond. There is a lot of tension but hard to find the releases. There are a lot of different and interesting melodies entering the fray at various points, but I'm not able to understand what melodic statement you're trying to make.
Also, your chords in the lower register are very dense and chunky sounding. I recommend studying some videos on chord and voice leading, as well as inversions and chord voicing. These will help you make the statements you want.
There are some places this piece shines like 2:03, but even these are muddied up with mix clutter, probably too much reverb, etc. Try turning down the FX wet and hi-passing your 'verb sends. These frequencies tend to gradually build up and muddy your mix. It's also beneficial to manage your different instrument reverbs via send tracks. I.e. create send track for appropriate 100% wet reverb, put reverb on the send track, then determine how much of each other track you want sent to it, and manage the volume of the send track collectively. This saves CPU too.
It sounds like there's not really a bassline going on as well. Most of the frequencies I hear could be played on a trombone or something, without an F trigger. A lof of the energy in tracks comes from the bass!
In short, I'm not sure exactly how to critique here, but recommend definitely checking out tutorials for the genres you want to produce, make sure to learn some music theory (it speeds up the writing process exponentially once you know the basics, and it only gets faster and better the more you learn) -- let me stop a sec and appreciate 5:08. Those first two chords are good. They work. Kinda chunky and condensed as mentioned. Third is wonky and I would change it out. 4th is just the right amount of nasty to sound jazzy.
Really, I would have liked to hear more in the vein of this outro. Six minutes was a long time to wait to get around to that -- and really, this part felt more well thought out than the rest of the piece combined. Extra half star for that.
