Pouffy pretty much got everything right on. I like your stuff, but found this one a tad boring. At times, it felt repetitive, and could feel empty sounding. I think some more supporting instruments to double up on the melody/harmony would have went well with parts of this piece, as well as adding some more filler instruments. I agree with pouffy about the dynamics, and I think that that is a big part of why it was kinda boring. I think next time you should use more louds and softs, and experiment more with pitch- using the upper and lower registers more frequently.

Pretty good!
