As a start, demo page is not loading

Hard to tell from the broken demo but the concept is not typically something suitable as there are thousands of these available for free online

what should i do, can i upload lightweight image file, why envato/codecanyon not clearly saying these are error found ,
they simply saying rejected due to technical quality . their documentation not so much clear. people putting so much effort to make something .
i think typing one line perfect reason in mail , is not so much hard work .

i think feedback should exact in mail.
