Always go back and look at your first 5 listed items in your shop. Do they own up to your standards now?
My first few pictures to me are horrendous. So before you go and renew those, update those pictures and revamp those descriptions, would you buy them?
I'm planning on making a list of pictures I need to retake and descriptions that need to be redone.
This is also a good way on seeing how much you've improved on your work, descriptions, pictures and tags as well.
Before taking that stop to the Critiques section, critique your shop yourself. Go to your shop in the shoes of a buyer and ask yourself: Would you buy it?
