I really enjoyed it, though it sounded a little spooky/ dungeon-like for me. The gaps between the chords could have been filled with more notes, or at least some long-lasting reverb effects.
While structure and sound could have been a bit better (I would have enjoyed a longer version as well), I think it´s better than any melody I´ve made to date. Keep it up!

It loops alright, but it really couldn't in any other way, as there is just too much silence. I feel the spaces between each chord are just way too big, creating an awkward silence wich I personally don't like. If you wanted to create a "slow and mysterious" atmosphere, I would suggest adding some reverb, but I really don't know that much about composition to be sure about what effects should you add... or stuff. Also, the piano sounds unrealistic, but I'm not sure if realism is what you were looking for.
on the other hand, the chords progression was good enough to keep me intrested on it. Keep practicing and uploading things, and you will eventually improve a lot, I'm sure of it.

By the way, I'm came here from R4R, but I'm not posting anything, so you should get another review soon. Have a good day! ;)
