Need critiquing on a composition I've been working on

[Saturn2888]

Currenty on revision 6.2 as of this posting, but changing by the days is my composition 1 Plus 2 which is a Marimba and Cello piece. The reason I've done such a strange construction of instrumentation is because I want to do it for a gig at the nearby theater and I have little that requires only 2 performers, I have stuff for 3, but not 2, so if anyone wants to critique it, it's here (http://www.freewebs.com/saturn2888/1%20Plus%202.mid).

If you wanna know the current revision, it's on the site which is freewebs.com/saturn2888

Any other versions besides the midi ones?

Well, if I had a marimba, I could make one, but I can't because my parents won't let me buy one even if I'll pay for it. See, the cheapest price is online, and it's $2200 for a good one that'll work for my music and my playing style.

Sorry. I could give you the score as either pictures in a RAR or as a Sibelius file. I can't do anything else because I have no way of doing so.
