It looks simple but nice. I think it would sell some but if they don't like it you can't do much about that. Make some changes, submit again, and if you get rejected write them and ask for specific feedback on what you can do. It can be tricky getting things published. Good luck to you.
Sorry if my comment looks a bit harsh, but I think the design is not complete. Menu, footer, pages structure, everything needs refinements. I'm a fan of your other theme – Vision, I think you could use some structural elements from there.
