Liked it! ^^ buuuuut...
You started off really well and the ocarina sounded incredible (that's a lot coming from me, and you will understand how anal retentive I am in a moment.) I'm not very familiar with ocarinas yet, although i do understand the idea. You may want to try different fingerings to get it more in tune on some notes... especially the last one (really reeeeeally flat.) Try to have the note "jumps" be a bit cleaner instead of sliding between the two notes. You go flat at parts (though that may just be the ocarina you are playing on not being completely in tune, but there should be ways to compensate for that, by doing something such as barely covering the hole you just lifted your finger off of.)
If you can't hear the tuning well, then get a tuner and just play with that for a bit figuring out what you can do to get it more in tune (any music store nearby should carry them and you eventually will be able to hear it better.) I really did like it though, and hope to see more in the future! ^_^
