Here's What I Think
I think the synths and trumpets are really shrill, try dulling them a little. Like you said, you could definitely add to the beat. The intro was too long, you should have stopped it at about 30 seconds or so. I can hear a lower brass instrument, but just barely. It would sound so much cooler if that were louder. After 1:24 it improves a lot, I'd say, but again, it repeats itself too much. The ending was cool, I liked it. Overall, it definitely needs improvement, but it has potential. Try making more than one melody, so it's mixed up at least a little bit.
