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.

We look forward to seeing more of your work.
