Nose and lips look the same to me. I think they've changed the facial structure slightly so that they suit her features more. She looks far more feminine now. I think one problem with the first version (and probably why people said she was a drag queen) was that the cheek makeup made it look like she had very high cheek bones. I think now she looks very subtle.
Funny thing is, I don't think the first 'coming soon' version looks bad. It looks good. But it's not Tanya. If this had been another character, I'd think she looks good, but it's just not Tanya, nor bares any resemblance to any version of her prior to MK X
