It's okay, the sound of the piano is a bit too rough though, for a credit song I expect something peaceful and/or; something that kinda says "hey, it's over" here it doesn't quite deliver that message, but that's just my opinion. But the lead that was introduced mid-way in the loop was pretty catchy, just try to make the loop transition to the beginning real subtly, an important part of a loop is to give the listener the illusion that a song goes on forever, here, I can kind off distinguish were the song ends and starts...

Now here's my real nitpick with this song: it's not House Music. I'm a bit guilty of putting a song in a category that doesn't belong myself, but then I began to learn what each type of music genre's key aspects are and now that's barely a problem now. You really need to research what's considered house music, because I'll be blunt right now; this ain't House Music, it has aspects of House Music but it isn't a full-fledged House Song, in fact, it's not a full-fledged anything, to be honest... This song would go under Other - Cinematic or, to a certain extent, Electronic - Ambient. I'm sure you're still learning this stuff (and trust so am I) so I can completely understand this rather minor error, but yeah, I hope I didn't sound too rough here... I'm just trying to point a fellow aspiring music producer in the right direction, hope this helped a little and good luck in the future!
