Funky!
First of all, since you wrote "another favorite of mine" I suspect that this is a re-arrangement of an existing video game music title that I don't know, unfortunately. But I really dig the tune. So, concerning your re-arrangement:
The choice of instruments and sounds is wonderful - except for one, the trumpet. It just doesn't really fit. Maybe this is just to me because I don't know the original, but they kind of annoyed me when they started bleating.
Also, making it a little longer would've made it much better, in my opinion. It sounded like it was composed of many different parts, and they blended into each other nicely, but that happened too fast. Since it's such a funky song, I would've loved to listen to those funky bits a little longer.
Still liked it very much!
