Sound Familiar...
This sounds extremely familiar. I made an RPG game a long time back, and used an obscure midi that I had no clue what it went to, I'm quite sure it went to some game or something. Anyway, the game I made had a song a LOT similar to this melody on it's title screen.
Did you base it off of something else? Or did you make this, to your knowledge, as a totally original masterpiece?
The middle part is kind of dumb though, the trumpets don't fit too well. Anyway, still a good job!
