I donīt think he looks like a Yorkie pup, the shape of the head is not right and the shape, size and position of the ears are not right.
The markings in the color are not in the right places and the color is not normal for a Yorkie puppy.
Here in Iceland almost all of the Yorkies are up to standard, and in the USA there are so many more Yorkies that maybe I havenīt seen enough Yorkie pups that are out of standard. So even if I donīt think he looks like a Yorkie he might very well be.
Here is a picture of Mandla when she was the same age. I put the pic of the pup beside to compare.
But he is a very cute puppy and it will be interesting to see how he will be like when he grows up if you decide to get him.
