I don't think the altered version captures the mood of the original face at all.
I love his current appearance and that it gives the feeling of a very calm, solemn sort of person, which has influenced how I've imagined the character since I made this initial design.
The updated face is harder to read, but the eyebrows have changed to be more slanted and more of a determined look instead of the very horizontal position of the original, in addition to being thicker.
The addition of dark circles under the eyes makes him look either tired, annoyed or "over it".
The face shape has changed in general, but I think people have gone into that in detail elsewhere.
Apart from the expression, the scar has changed from actually looking like a jagged cut on the face in the original model, to a textureless brown line that might as well have been painted on.
I forgot to take an additional screenshot, but if the left side Duskwight tattoo is turned on, the scar slashes through it and breaks it up. Again, in the current model that looks convincing, but in the changed model the brown line looks just as flat as the tattoo.
