OP - It's awful.
You need to really listen to what your band is doing and if you can't hear what's wrong, then all hope is lost regardless.... just the fact that you not only uploaded this to youtube, but actually enrolled in some contest tells me that you have no idea just how awful you are. I don't know which person you are in the video, but I could point out at least 5 points of necessary improvement on each member, starting with musicianship being the number 1 issue equally needing attention from all of you.
Work out the kinks - get it together, get a better recording, and get back to us. It will take time and dedication, but ask yourself this:
Knowing it could take a year or more to get this band capable of doing high quality gigs, with countless hours of practicing and rehearsals each and ever week, do you have what it takes to follow through and take control of the situation and make it better? Do you have enough of an ear to hear what's wrong? Can you learn from other bands what does and doesn't work (at shows, not on the interwebz) ??
It takes dedication and work to make a solid gig-worthy band, and it takes a lot of patience and compassion, and compromise to keep a working band together. It's not easy, and it's not all fairy tales. It's 90% work for 10% reward. If you find the reward is more than 10%, you are either doing something wrong, or you are a blockbuster platinum artist and wouldn't need my lousy opinion.
This was not meant to be incendiary or mean, just openly, and brutally honest. I wish you the best of luck.
