Well...

I really loved the melodies. The simpleness of using just a marimba for most of piece really worked most of the time.

I somehow felt that somewhere around the half-way point it should have... become more expansive, I guess. It didn't, so it felt to me like the piece didn't really try to go anywhere.

Also, the piano texture didn't really sound very nice with the marimba here, in contrast to the other instruments - maybe adding another marimba might have been better.

But as I said, I really do love your melodies. My score is a mix between the first part which I quite liked, and the second part which I felt should have been a little more than it was.

Check out some of my pieces, by the way. I use marimba a lot. :)

really cool!

I liked it! It's actually very relaxing, keep up the great work!
