Please help me why this item has been rejected?
hi it looks not bad, this is rather clean in my view
though, i tend to believe that, if u want to bring your item to the next level, u may try to make sure that the hierarchy of information is more determined, as well as u may try to make sure that titles pop up a little bit more. Finally, i tend to believe that for this type of flyer - corporate style - it would be better not to have the dyed colors in the left and at th bottom as, not only is it making the thing slightly less readable, but this is not really matching with the needs of this kind of item
Thank you
u are welcome 
try to do this and try to resubmit
