I looked through the comments, and I hate to be the one person with something negative to say, but this sounds like two completely different songs. In my opinion, it would have worked a lot better if you had separated the two. It feels a bit like you have two puzzle pieces that you are trying to put together that don't fit.
Also, it doesn't loop too well. I can easily tell where the loop ends.
Although, you a did a great job with the song in general. From 0:00 - 1:00, it felt really calm. Would sound nice if you were running through a village or something. Definitely got the grassland feel out of that. From 1:00 - 2:16, I was kind of getting a desert theme out of it. Would work well for a festival or a larger town as well.
Sounds amazing, but I definitely couldn't see it working in a game unless you cut it in half.
