ChristinaB,
When compared to the Sewell print above, there are a few things that you should keep in mind when selecting a male for your hens.
First off, a couple of your hens have a topline with a break at the tail. The tail angle is too high. The topline should be almost horizontally flat through the tail. The hen in the last photo has the best tail angle. Unfortunately, she looks like she might be the smallest of the group.
Color... I am seeing feather shafting. I don't know what causes it or how to breed it out, but it seems to be a common problem with today's SS. The color is not as defined as it should be. The white is blurry in some areas and all different sizes. I think the tip of the tail feathers should be darker than they are.
Type...I am having a hard time with type... I think there is too much fluff on the butt. I think we should see tighter leg feathering in such a manner that the legs are noticed. Your girls have so much loose feathering on the bottom that the legs just look like they are part of the underline... Man... I don't know if that is going to make sense to you.. Sorry, I did the best I could on explaining that. Perhaps, Don will pop in here in the next day or two and do a better job of explaining what is wrong in this area..
As far as quality or showing... My local chicken show has not had any large fowl SS for 4 years straight. I have a tainted view because of this. I feel a hatchery quality SS is better than no SS. It sounds like you have a lack of SS in your area too. So, go ahead and show them. What's it going to hurt?
You will get experience with the actual showing procedures, PLUS you will get feedback from the judge.
If there are some really good, top of the line ss there, then you will get to immediately, in real time, compare them to yours.
Winning at a show is good. Learning at a show is even better
