That’s some brass sound, if I ever heard one. Quite literally :D.
Simply love your created brass synth sound. Your composition is simple but elegant. Just those brassy pads, a deep drone and some Kalimba like melody that paints a beautiful vista. Though I have to say it felt a bit samey. Tonally there was some buildup and change and at the end you even established some additional instruments. But I think it needed something more. Maybe having the drone changing gear and shifting it a fifth up or down and creating a more dynamic by letting those Horns roar would have kicked that changeup into a well deserved climax. Or even adding the fuller orchestral sound of the BBC Discovery for the emotional finale.
While my critique might sound a bit nagging, I need to emphasise, that you did a quite solid job and the simplicity of it was genuinely great. My critique here is just to point out what would have made it excellent in my view. So keep it up and hopefully let us see more what you’re able to do in those jams!
