Yay!!
TUNE!!!
Shweet track you've got here. Loved the new sounds you have going here :D
I think for me, it could have used some drum samples that were a bit more unique. Granted, this is coming from a guy who has to listen to all the samples Sam comes up with lols so I may be nitpicking. The mixing was pretty good (watch your peaks - it sounds like it's close to clipping on the kicks) and I could tell the amount of dynamics you put into this. It was awesomesauce, so it's a small complaint about the samples and potential peaking.
I also think it got a tad repetitive - while you switched it up at the end, I think you could have either condensed the song into about 3 minutes (shortening intro and reducing the amount of bars per pattern) or you could have introduced some elements. The parts at the end were pretty shweet :)
In terms of introducing new elements, maybe a shweet pad to add BG ambience or a more defined lead. The Square lead you have in there could have been made either dirtier or have been paced a bit faster to make it vary a bit.
The song feels like it grows throughout. If that's what you were going for it works, but there's no ups and downs here (chorus/verse or lull/climaxes etc). So that may be one of the issues for me.
So the song's definitely epic man! Once again can tell the improvements you're making :D Looking forward to your next track!!
