Thank you for taking the time to submit your item. Unfortunately this
item does not meet our quality requirements and cannot be accepted at
this time.

The item does not meet our minimum design, animation, and technical requirements. We strive to accept professional quality projects, and unfortunately this submission doesn’t quite meet that criteria.

When reviewing projects, in addition to overall quality of design and execution, we take into consideration the flexibility, usefulness, appeal to a broader audience and broadcast readiness of the file. Unfortunately we don’t feel as though this project meets the standards we have set for these criteria.

What else do I remake?
