The answer depends on the case. Quality Control revisions will not be awarded any extra payments. Such is so because your original submission did not meet our client's standards according to our Quality Control team. Keep in mind that only approved files will be awarded payments.
We expect Pros to only charge extra for revisions when original remarks were modified, or when our client has made adjustments to the original brief provided. If the revision requests you to place more emphasis on an intention, or follow the remarks more accurately, there shouldn't be a further payment.
Bunny Studio works on an honor system; we trust our Pros to charge what they believe to be fair for the revisions, taking into consideration the initial reward accepted when the project was offered.
