need suggestion for opencart theme

My theme http://themeforest.net/item/justshop-cake-bakery-opencart-theme/14711702?s_rank=5 is approved but there is no single sale yet.Please reply with your suggestion to improve sales.

Its really unfortunate to see this. Remove the wordpress banner from your item page. Wordpress version is making hell good sales so may be your customers are also diverting to WP version
