luvchicks8, you need to find a judge/registrar/breeder that you can trust, and get them to teach you how to size up a rabbit. It seems to me that the person you are dealing with either doesn't know Hollands very well, or is counting on you not knowing them.
The first bunny doesn't look lilac to me, it looks like a slightly sunbleached blue. It appears to have a nice profile, but I agree with everything dbunni said about it. Holland Lops are posed sitting up, like a dog sits. The good ones sit like that naturally. The ones that tend to hunker down are called "rug munchers" by a couple of breeders that I know, lol. While you can teach one of them to sit properly, they usually have weak shoulders or other defects that won't let them do well on a show table. By 5 weeks, the rabbit should have ears that are down most of the time. A truly SQ Holland shouldn't be able to get both ears over its back at the same time, most of the good ones can't lift much past horizontal by this age.
Judging a rabbit is a very "hands-on" process. Because they are so fuzzy, you really can't tell a lot from a picture. The pose can make or break the rabbit - I remember an article in Domestic Rabbit where the author presented three pictures, and asked readers to place the rabbits in a hypothetical class. At the end of the article, it was revealed that the three pictures were all the same rabbit (a New Zealand White), just posed slightly differently in each shot. It's funny how just placing the feet slightly forward or back of the ideal position could make a grand champion doe look long and flat, or chopped off. You need to set them up properly, and then let your hands tell you what is going on beneath the fur.
In most rabbit breeds, the vast majority of points are awarded for type. I'll have to check to be sure, but I think something around 50% of the points for a Holland are awarded for things that happen in front of the shoulders. In the Harlequin breed, the majority of the points are awarded for markings. Because of that, a lot of breeders concentrate on the markings, and pay little attention to the type of their breeding stock. A lot of Harlies are scarecrows under those wild markings. I remember putting a buck with only adequate markings, but a great body, on a show table one time. The judge bred meat rabbits, and his disdain for our breed was evident. When he got to my buck, he looked him over, set him up, ran his hands over him, and the expression on his face changed radically! He was shocked to find a Harlie with a body like that, but he didn't know it was there until he felt it. Knowing the point breakdown, he had to put my buck in third place, but he told me "if they were judged by type, as they should be, I'd have given him BOB."
