I really like the introduction! Maybe a tiny bit long but still pretty good. This is just me, but to me the bassline is a bit meh and kind of gets drowned out, but at the same time it does have an interesting effect so if thats what you were going for then nice work :) Anyway, the review:
+The intro is nice
+The general backing rhythm is pretty strong
+Mastering is pretty good!
+Pretty good drum samples! Maybe a bit quiet in places. I do like it though.
-Im not so sure about the lead synth at the start, to me it doesnt quite fit. Though the one at 2:05 works a lot better in my opinion. Perhaps make it softer and change the saw type. Again, just opinion.
-Some changes or development in the backing rhythm could have been interesting, but it comes down to how closely you want to follow the original so again, just nitpicking.
But anyway, pretty strong track! I like it alot, just personally I would have done some things slightly differently. Keep up the good work though!
