That's fine but he already had a very good design. And it was iconic. There was no reason to change it, other than the sake of changing it (which seems to be a reoccurring theme with this remake).

Facial mocap technology has advanced enough that the character doesnt need to look like the face actor at all, so there is no technical reason his design was changed. His voice acting is probably the best in the whole trailer, but I still much prefer the delivery of the original.

They're trying to put way more emotion into the acting, which is going to absolutely RUIN when Mary reads her full letter to James at the end of the game. The "bad" voice acting of the original, with the mostly deadpan delivery, was vital to making the beautifully emotional delivery of the letter reading stand out and evoke more emotion from the player. It's a special and nearly intimate moment the player feels because they just spent the whole game with barely any visible or audible emotion at all. Adding more emotion will only take away from that.
