Never used to get any rejection and just last 3 days I have gotten 20/22 photos rejected for reason of "photo not unique" enough or "not up to our standard"... I can pick many more photos that are way below standards of the ones I submitted in last 2 days that's been accepted without any issue...
I'm sure if you keep trying to improve the outcome of rejection, surely canstock parties will easily accept the results of your photo.
I have always received helpful suggestions about improvements to be made. Canstock parties will continue to help. Thank you Canstock.
