Actually I like white and clean style but honestly the site looks unfinished to me somehow (I thought the CSS wasn’t loaded at first). And I think that the overall design of the site is scattered. It looks like the elements don’t match with each other (like the body and header). Maybe because they hadn’t been initially designed together in the first place? They might need some refinement in my opinion.
But it’s good to see the changes and movement. Keep it up!
November is a great month for me but as FinalDestiny said, the sales dropped in 4-5 days lately.
Did you mean to purchase a plugin from CodeCanyon and use on your WP site? If so, then yes, you can surely do that.
