First Piece, CC?

I had to make a Carl Orff music lesson for my music education class, and I've never composed anything before and am just beginning to learn music theory and would like critique and comments. I had to keep it very simple so the class can play every part. It's basically a new rendition of In the Bleak Midwinter. I tried to make it a tiny bit bleaker. Anyway let me know how it is.
