Pretty good, really authentic video game music
However, you could do more with the strings at the end part, by varying the rhythm (you had a pause, then it played every quarter beat) ; in my opinion, it subtracts from the work a little, and it might be worth experimenting. Other than pretty good, though I think you could take the theme further and follow up on some ideas; one of them ended at 0:15 a little abruptly.
Nice composition here. I can definitely see this in an RPG game. I like the way you use the brass instrument.
Please contact me if you would like to use this in a project. We can discuss the details.
