Well this is my first post on these boards, so I'll introduce myself. I'm a college student who plays piano and violin on the side, and also writes a little music! I've been playing around on Finale '11 for a year or so now, and have written a couple decent arrangements. Here is my latest - an arrangement of a really cool (and less-known) hymn, for string quartet and keyboard (might rewrite for harp, though).

Things I'm wondering about:
-is the intro ok? and does the transition into the main melody sound awkward?
-how does the harp/keyboard part sound? I've already sat down and played it through - so I know it still needs some adjusting.
-How is the overall structure of the arrangement, and what could I do to improve on it?

Any comments or constructive criticism is appreciated!

A string quartet with keyboard is a piano quintet surely?

Ah, good point.
