HTML,CSS version approved but Wordpress version hard rejected , why ?


This is email which I get from Themeforest team `
"Unfortunately ‘WordPress’ has higher standards in terms of aesthetics. An approved design in other categories does not guarantee an approval under ThemeForest WordPress category. Your design has an interesting starting concept, but it needs significant improvements in terms of aesthetics and attention to details.

As higher quality items become available in the marketplace, approval requirements will increase to maintain appropriate marketplace quality.

While I’d be able to provide feedback as to how to get this approved, I can only do after it has crossed a certain threshold, quality wise. I’m sorry to say this isn’t there yet."

Please can somebody tell me why my item not approved in wordpress corporate category ?
This is theme url:

I selling html,css version of this theme in themeforest this is link

but why they not approve this item in wordpress category like wordpress theme ?

But I can’t understand which part of design not aesthetics and on which part of design need more details for wordpress category?
