sounds good. the trumpet makes it sound a little rough though. maybe you could replace it with something a little softer- unless you want it to sound rough.
This is a neat little piece you've got here. I like it quite a bit, and I don't mind the tuba; I think it works pretty well as a bass line. The only thing I would suggest is accenting the notes before the sudden rests more, and maybe even coming in a little more softly afterward with the lead-in tuba notes to give those sections more of a sense of shape and purpose.
Yeah i think it needs something softer in the background , a flute or violin or something airy and soft, kind of unoticable unless your listening out for it , yet ties the rest of it together
