Hey, man. Been using this site for almost 20 years, but I finally decided to create an account so I could comment on this. Big trance fan, and big fan of DKC. I really, really like what you've done here, and I had never even considered someone doing a remix of the part 2 portion of DK Island Swing. Really sick idea! I wanted to comment, though, because, in my humble opinion, you're trying to do a lot at the same time in the way you added in the part 1 (beginning at about 3:30). I've found that trying to do too much in a trance song can take away from the flow and feeling of it, and I personally found it a bit jarring. I don't think it's a bad idea to include the part 1 melody, but were I you, I'd be more subtle about it. I think if you layered it over the more developed beat you have going on from 0:15-2:05 with a some kind of more chill instrument, you could still squeeze it in there without trying to do too much. Two remixes that I think do this well are Focus, by DarkSim (also a DKC remix) and Terror Plant, by CromzonWolf777 (actually a remix of the same song, but a more similar in style to yours).
That all being said, this remix is your baby, and please don't let some random guy on the internet tell you how you should and shouldn't compose it. If you're happy with the way it sounds, stick with it! I'll likely add it to my library either way ?.
