I have to admit this one is pretty nice. You use the "dissonant" chords really well and you have a good grasp on when to use them effectively. My only criticism of this is that it also is too long for what is there simply because it just kind of repeats again with no real difference until the end. It's a nice piece, but I would recommend trying to fill it out more and try to do some more variations to keep the listener interested all the way through.
But overall good work!
Also, these are just midi files, you don't have to upload them to mediafire. You can just attach them to your posts.
