My male Sheps [http://www.masseffect2faces.com/index.php?faceID=534] always had my own first name (David), green eyes, brown hair and brown armour (w/ dark brown camo decal) and alternates between a van dyke or stubble (wish there was a proper beard option). My female Sheps [http://www.masseffect2faces.com/index.php?faceID=532] have usually been Kate as it happens (tho I now I feel like a cliché), green eyed, red hair (actual red, not ginger) with deep red armour. Both almost always wear the Sentry Interface (occasionally Recon Hood) since it's the only headgear I like the look of (I modded it in both games so the game flags it as having a rebreather (so Shepard can wear it even in a vacuum).
They have ALL been Vanguards. Every single time. My next one will also be a Vanguard as will the one after that. Because nothing says "I love you" better than a Biotic Charge and Claymore blast to the face.
Those pictures aren't as good as they look in game, or strangely how they looked in ME and ME3, both of which looked better. ME3 in particular with a hi-res textures mod, the characters looked much better.
EDIT: I just remembered that one downloaded save I used for a playthru I forgot to mod the name when I changed his class in a save editor. I did have one playthru as "DonutsFTW Shepard". His armour was hot pink; his Claymore was not.
(Wow, I posted a similar story [http://www.escapistmagazine.com/forums/jump/9.299439.11899821] in an ME thread on this very site three years ago!)
Just found the save actually, still on masseffectsaves.com [http://www.masseffectsaves.com/mpsl.php] about 15 down. Was a Paragon/Liara run.
