Roxy looks a lot like my Abby, who is an AKC yorkie with a lot of silky terrier attributes. I have been thru the posts and info from Carmen (Thanks again!) and even tho Abby is "only" 7 lbs and very petite the biggest things that seem different about her are the shape and size of her feet and nails (cat like) The way her ears stand up at the base. The length and shape of her body- especially hips and tail joint. A difference in the shape of her forehead, snout (pointy-er). And of course attitude- the sweetest, easy going pup in the whole world!
