I settled on using the Shepard imposted, and actually, it looks much more like my character in-game. It’s still a little off, but it’s close enough. As it turns out, there is quite a large disparity between the way characters look on the character creation screen, and the way they look in-game. It’s unfortunate, especially for those people like me who are trying to recreate a very specific character. You’re not seeing it in the creation screen, but in-game it may look a lot better.
Anyway, here’s my Shepard in-game. I’m satisfied enough that its him to start playing. The minor differences I’ll chalk up to age and stress.
