having a quilt critiqued should be a learning experience. Judges are not out to dis you or make you feel bad or incompetent.
Do some research on the category you were in and ask to have your concerns explained. This should make the judging clear for you.
One time, when doing a panto, I mis aligned the repeat and the following run was a few inches out of place. It made a small but noticeable gap between the runs and thus, I learned to check twice, quilt once!
Don't give up on entering quilts, there is so much to learn and enjoy and create. It is all good.
