What's the reason for rejection of this theme?

Hello mates! I’ve been trying to upload for a couple of times some of my work. At the moment I’m working with other 6 sites were my music it’s been accepted. I’m very curious about what do I need to do to get the approval on audio jungle. Is the quality of my tracks really bad? does anyone can give me some feedback, please? I’ll be very grateful to read you guys. Best regards!

here you have some tracks of my music (I don’t know how to upload here, so I leave you the links where you’ll find the tracks):
