I attended a lecture some time ago by an NQA certified judge about what judges look for. The handout we received lists these items under the section for quilting (notes in parenthesis are a summation of her discussion of particular items on the list). They may give some guidance to the OP and anyone else interested...or not. Just thought I'd throw them out there for anyone interested.
Quilting
Does “quilt-in-the-ditch” stay in the ditch? (the ditch is always the low side, never the high side. Plan ahead when pressing seams as you are piecing the quilt)
Is the amount of quilting consistent across the quilt?
Are all quilting marks removed?
Are quilt stitches even in length? (size is less important than being even)
Are straight lines straight and curved lines smooth?
Do all quilting stitches go through to the back? (are there any tension issues?)
Are starts and stops unobtrusive? (burying knots is the best way)
Are travel stitches invisible?
Is thread color appropriate?
Are quilting designs well chosen? (do they add to the quilt?)
Do quilting designs fill the spaces well?
