I’m not a designer but it doesn’t look up to the standard for Graphic river
-
The mock up versions look pixelated, days can’t be read clearly, the grey background does not help and the angle of the item feels obscure
-
The typography esp. the days doesn’t look great
-
The main image feels like it has a lot of unnecessary space above/below it
-
Padding between the image and year feels very cramped
Generally it just doe not look premium quality and looking at the recent calendars uploaded and approved they all feel more unique, have stand out features and a much higher level of attention to detail.
This is probably why the reviewer didn’t feedback - because it’s just too basic and far off the standard. Even if you fixed the typography then the design itself is still not really strong enough.
