Sweatshirt for ebay customer

For some strange reason, the Greek letter designs I purchased aren't stitching to my liking.  I've tried two different embroidery design companies.  This posting is for a customer who purchased a sweatshirt.  I'm posting it so she can determine if she is ok with the stitching.  Thanks. 

The Z stitched out perfectly but the Deltahad some loose stitches.  I cut them so they should stay in tact, but I'm not satisfied.  If you still want this shirt, I will sell discounted.  Thanks so much.
