On the whole my experience was a great one. I would like to point out a couple of things. I did find that some of the designs were not entirely original. Maybe if designers had to submit a design before they see what everyone else has submitted so that they don't just reproduce what others have submitted.
This would also prevent dialogue on copying, which appeared in my competition by a designer who then promptly withdrew her 11 designs! After a follow up email from myself she resubmitted, but it left a not so pleasant feeling in an otherwise exciting competition.
