The opening is beautifully atmospheric. I love it.
Slight pause at 0:24 which really threw me off, but otherwise.... that sax melody, maaang. <3 It's not the sound of the sax, but just how well done that melody is done.
1:03 or thereabouts has a quirky, Waterflame-ish feel about it. I don't know what it evokes to you, but it brings to mind atmosphere, water and wind all moving in the same fast pace.
2:10 or thereabouts, I don't know what to feel about the slight tempo changes. But otherwise, I love what it sounds like.
2:23 -- Love the melody, but I don't know what to feel about the complete and utter change in feel there.
It seems that you've been experimenting with several feels of one piece before settling with one, the one that appears most, at both 1:03 and 3:00. I don't know if that is what you intended, but it certainly comes across to me as such. And outside of the iffiness I sometimes have with the complete changes in feel, you did well with repeating chords and melodic motifs -- you built up well, you seem to have the mastery of music within your grasp.
A solid 4 from me; well done.
