Help file

Hello everybody!
Not long ago I submitted my very first item on GriphicRiver, however it was hard rejected (quality reasons).
My question is: Can this quality rejection be because of the help file? I don’t really konw how to make this help file.
Should it be more like a tutorial or more of a general presentation? I need to mention that my item was’t a very complex one (it was a 3 layered image and i did explain each layer)
Thank you in advance.
P.S: sorry for my bad english.
