Oh this one as well. So well done! I'm gonna leave my thoughts for you to consider or dismiss, whatever you like.
1. Have you thought about making it without Andersson in it? I think that might be even better. Quote is great though, it's just Andersson that steals a bit of the awesomeness of Shepard in this particular pic.
2. My eyes latched at the bottom letterbox that could be evened out with a fully black top one as well. All is artist's choice but there's my two cents.
I actually have been thinking about redoing this one because the model I used for this piece (which is one of the first mass effect pieces I did) isn't the default shep mod. It's nagging at me for so long now.
