Hard seas? But water is soft XD
So first off, the synth choice at the beginning is good -- it's a little edgy and aggressive, kind of like a storm at sea, no?
The bass coming in with the kick is cool and ominous, and really works with the tempo increase. Unfortunately, I would say that the song is too slow overall, but only by about 10 bpm or so.
Whatever the hell happens at 1:06, I like it!
At 1:23, things start to get, well, "wavier" is the only word I can think of, but that just again shows what a good title you picked, so good job on that.
A lot of your songs, including this one, seem to be laden with this weird, wavy kind of reverb. I normally don't have an issue with it, but there seems to be a tad too much in this song. If you don't know what I'm talking about, take a listen to the first 20 seconds or so of your "Enigmatic Hills". I actually don't have a clue what it is.
The melody is good for this genre of song -- hypnotizing!
The kick drum rhythm change at 1:57 I don't mind, but it didn't have to be there to enhance the piece. Just a matter of taste, I suppose.
At 2:45, that high synth that sounds like an organ is a great addition. It disappears at 3:00 for the outro; this is a good length for a climax of a song (15 seconds), because any longer might be too much of a good thing, a little overpowering in general, or it may ruin the flow of the piece altogether. You seem to have a good knowledge of song structure, which is something important that quite frankly, I need to work on myself -_- lol
Good ending, too!
All in all, this is pretty good; it's just not my cup of tea, so to speak. Whatever, we've all got preferences, so I'm not going to complain.
Keep it up, dude. Good stuff.
If I had a boat, I would sail these seas. But boats are too expensive, so never mind.
