You're one of the few people I can think of who can make a song that both uses chip tune elements and is still relaxing and trance-like. Bravo.
My favorite part of the song was easily the transition at 3:03. Glitch noises FTW! The synths you used may seem similar to those you've been using recently, but I disagree with BlueOceans. You can use the same instruments over and over again and still come up with interesting tunes. Why else would people keep listening to orchestras or piano concertos? (I do get that there's a bit of a similar feeling between songs recently as well, but if it's not broken...)
Dislikes... hm... Well, it's sorta hard for me to say anything bad about it, as I've been relaxing to it since about yesterday. I guess that the synths at 1:22, when they hit their loudest dynamic, cross the 'too loud' barrier by just a tad (probably because they're being layered). I also think that the claps were a bit too loud to serve their purpose, save spots like 2:32 where they're used every quarter instead of every eighth.
I also found it ironic that you tried not to use white noise and rev cymbals in your buildups, and yet, I think white noise would've made it better in the form of wave-like noises to emulate the sound of the sea even better.
Keep working on new things! I enjoy it when descriptions like that are put up, since you can see the thought processes behind the author's work.
