Not finishing is for sure a problem, but Damien didn't follow directions because he didn't know the techniques. IMO, that is worse in a competition like this where technique is vital. But someone who works like Farie just isn't a good fit for a competition show. Running at her own pace, I'll bet she could produce great looking items.
The missing zipper guard seemed very scripted to me.
I didn't like Rebecca's Dior look at all. Nothing about it said Dior, especially the floral fabric mixed with a solid. It wasn't well made either, which was surprising.
