Well...
First off. I like a lot of what's happening here. The beginning starts really nice and subtle with the bass and drums, which is nice. Then that guitar comes in. It's nice, but it sounds like there's some reverb on it giving it a distant feel and there's also this ring coming off of it. As soon as other parts start playing within the song the ring isn't as noticeable which is nice.
Next thing I noticed was a lack of energy. You've got these nice parts that sound like they're lacking. I'll give an xample. 1:42 - 2:30. That sounds like a major build up, but it's lacking suspense so when 2:30 does hit I'm not really surprised. When 2:30 hits, that's when the song should affect me the most. The drums are mostly the same is sound throughout the entire song which may affect the energy experienced. Just go back and mess with them, don't be afraid to play with the rhythms. There are also other ways of dealing with this.
Overall, I can say I liked a lot of what was going on as well. You've got some fun melodies that are going on all around. The song is actually relaxing for the most part. You use a variety of effects which turn out nicely and are used well for the most part.
Keep up the work.
