First off, great work!

Production-wise I think the intro guitar sounds a bit treble heavy but it sits well through the rest of the song. And I feel like the part from around 1:35 could use more energy/volume in terms of the instrumental backing.

The chord changes are pleasantly interesting and the vocals sound nice. I guess going back to my comment from earlier, I feel that you can get away with letting the instrumental be more dynamic because the vocals seem to call for it (at least in my opinion).
