Sorry if it sounds harsh, but you may want to consider starting from scratch. Your theme is lacking quality and sometimes it is just easier to start with a blank canvas then modifying an existing one. Goodluck!
Think outside the box. Do something that you have never seen before. Create trends instead of following them. BUT, be careful when innovating because it is risky and not always accepted by the community. However, when innovation is successful, the rewards are huge. That is why it is important to provide more traditional and widely accepted versions of your layouts included with your theme as well.
Hope that helps.
Very clean design. I feel lacks a bit of character and uniqueness.
I say keep the navigation! Its unique. BUT, you should also have an option to switch to a more classic nav style if desired. Good luck!
ps – God damn that scroll bar is skinny!
Your design layout is very cluttered. Your throwing too much information too fast in my opinion. Try adding more white space and let the design breath.
Hard rejection on this theme is pretty harsh! I’d say it was just bad luck with the reviewer. I wouldn’t give up, you clearly have talent, just keep trying new things.
