Will,
I'm just listening again as I read your comments and can see what you mean.
However....this was intentional, as a sort of 'echo' style to attempt to supplement the main instrument without detracting from it, if you understand.

This is why I would like to have an extended version.
My opinion (FWIW) is that a musical theme should be allowed to develop so the listener recognises the structure......then let that structure support a bit of 'interpretation'. If the interpretation is applied before the poor listener has 'got his lugs in' (as they say in my part of the world), it usually makes a mess of the main theme.

Anyway, I enjoyed doing this and would like to take it further. (by the way, I quite like the 'clarinet')
At this point I can hear just the whole repeated.....unless you can come up with a suitable variation....maybe a longish bridge section then finish with V3 and V4.
Thank you for your music.....it's lovely!

James
