They look pretty good. I don't see any DQs. Just make sure they have 5 toes. Having less or too many toes is a common DQ. The partridge hens look particularly good as far as type and crest fullness. The white ones' crests could be bigger and cover the comb area more. White silkies are the most common, so showing them is extremely competitive. It really depends on what level you are showing at (fair, state, national, etc). I don't breed partridge silkies, but I know there is specific coloring that they must have. It'd be a good idea to look into that or maybe someone who breeds the partridge ones will chime in. If you want to seriously get into showing I suggest buying the ABA Standard Of Perfection book. Here is a link to a summary of the Standard of Perfection for Silkies:
