Creations don’t have a set time to be approved or denied because it entirely depends on how many are in the queue.
You won’t be informed if your creation is denied nor will you be told why, that’s just the way creations works.
So approvals can vary from hours to a week or more.
All I can suggest is to be patient, and then if it’s been over a week, you can submit again.
But submitting several time over a day or so does risk your entries being denied just because someone may think it’s already been approved when they see multiple.
