First of all, good composition. I like the overall makeup of the song. I like how the time signature changes up. The song is not predictable. I like it.
I doubt anyone will ever listen to this again though because it sounds Nintendo-y. You know. Computer generated. Oh well. You do your best with what you got to work with, am I right? Good job.
Please contact me if you would like to use this in a project. We can discuss the details.
