The overall instrumentation and composition make it feel very much like a Zelda game or an early Final Fantasy. Each instrument clearly serves its purpose and helps drive the song. The rolling snare serves as percussion and adds to the sense of "moving forward." The cymbals help control the energy in the transitions. A loud and proud brass section drives that main melody home, while the strings playing quietly in the back lends to that feeling of it being an expansive world.
Overall, it is a good piece. Depending on what sort of game you wrote for, the direction you need to aim for varies greatly. I have no problem picturing this playing while running through the fields of Hyrule. There is a lot of action going on in this music, so the game would have to be pretty action oriented. On the other hand, most JRPG's feature a grid system with limited movement, meaning you might want something a little less exciting, but still just as adventurous.
The mix is good. I can hear every instrument playing. (snare, bass, cymbals, brass, bells, strings, and maybe even a choir in the back?) However, I would recommend adding some slight automation to emphasize the main melody just a bit. Also, bring the bell volume down a little bit.
Anyways, its a good track! Keep up the good work!
