Miniature concerto for bassoon

Hi to all.

I've recently been asked to write a 5 minute piece for chamber orchestra, prominently featuring the bassoon.
A sort of mini bassoon concerto if you will, for a concert next summer.

Here's what I have so far.

Only started writing it two days ago: so it's not remotely finished, and I haven't put in slurs or articulation yet.

Some of the dynamics are just for the midi playback.

Wanted to ask my fellow composers if you think it's any good? And where it needs improvements?

As usual I wrote it mostly by instinct, and didn't really think much about voice leading, or harmonic progressions.

As some of you know, I quite like sparse textures; but I wonder if it's a little too sparse?

Also whether it features the bassoon prominently enough to hit the brief?

A critique of my harmonic progressions and orchestration would be very helpful.

Also I don't have a name for it yet: so any suggestions welcome!
