I think you have done a fantastic job with the two girls. I can actually see the likenesses in both to their original. The new Anna's hair is fairly similar to the original, and the only differences I can see are her eyes, they are bigger and also her lips appears to be bigger, also her eyebrows are a different shape.
Lena looks very similar to how she really looks apart from her eyes, nose and mouth.
Overall I think you have done a fantastic job in recreating them. I don't think anyone who hasn't play my new memories would know who they are at first glance. They are very similar. The originals are still the best as you say, probably because it was those we where introduced to in the story and got used to.
Can't wait to see what you come up with for the next couple of girls!
I was actually wondering if the shrink and samantha would be part of his 'harem of girls he regularly has fun with?' maybe fun is a bit over the top hehe
