That seems awfully downtuned.
I liked the mix. If that was a drum machine, nice samples. I liked the
backing track, but would probably rearrange it to reduce the drawn-out-ness of some chords.
I found the intro a bit slow (tempo), and lacking a stronger intro. I would play some of the "lead" you did on top of the intro, starting after the first roll. That part sounded quite empty, since I expected some "playing" already. Reminded me of Tom Sawyer at the start and Emerson Lake and Palmer as well at some point.
I found some parts of your solo repetitive, but it could be because I'm listening to it in a loop. I liked the part from :50-1:00. I would vary the playing at 1:04-1:07 and NOT repeat it at 1:23-the end.
Nice though. IF you can play fast, I would recommend to play faster towards the end.
