I am really impressed at the quality of your production these days! It genuinely sounds pro.
The bassline again: it sympathetically resonates with my sternum in a very good way. The drums are simple but help drive the track along, the real star are those horns...the envelopes must have taken you ages! I can absolutely hear this as a track in a modern film score.
If I were to add anything personally I might include a bit of piano or other melodic percussion in the last third of the track to create more of a crescendo using different textures...but thats a style thing rather than execution.
