I don't think Tanya's face looks deformed. I think her design lacks, especially compared to her original design.
Modern MK seems to be inspired by recent popular series/movies and likes to turn their characters into whatever inspired them. Tanya inspired by Wakanda forever? Idk, but it looks like a trend within recent NRS games and im definitely not a fan of it.
The problem for me, and maybe other MK fans as well, is that the characters and lore were previously inspired by martial arts, Sci-fi and horror movies. Modern lore and character designs seem to be inspired by different themes nowadays. I understand that NRS follows modern media and use that as inspired material, but the gap is too big with what it was initially inspired by.
This somehow devided the community and we see that return in the feedback towards new MK games. As a hardcore fan of the older games (MK1 - MK9) this is really frustrating and saddening..
A series you love so much and grew up with seems to take a direction far from it's origin that doesn't click. I wish i could say otherwise.
