Not sad. Not really.

I think you should look into your heart a bit more closely and see if this music correlates to being sad. 95% of people will tell you that this is NOT in fact sad in any sense of the connotation.

As well, this feels sloppily produced, a brain-storm idea that you didn't want to throw out completely. This could have been the segue into a decent-to-mediocre song, but as it stands, this is barely worth consideration.

Focus less on 14 second loops expressing feelings, but rather, focus fully on the emotion you wish to convey and all the musical ideas that come with it.
And get better soundfonts.

I wouldn't say sad.

This has more of a "japanese horror movie" feel to it and it makes you feel there is a spirit lurking around you.
