Your pups are very cute! You can see here on YT that yorkies vary greatly. You can never really tell for sure what they'll look like full grown. Be prepared for their fur to change many many times. Here's pics of Uni when she was 12 weeks (first day we got her), then in her akward teen years, and now at 2 years. Don't be afraid when you have to cut off their black fur. It is a shock the first day!
Remember to trim the top third of the ears so they will stand up. There is a thread for pretty much anything yorkie on this site.
