I'm on the PS3 so I can't post screenshots or anything, but I prefer my Shepards to look a bit boring. Genetically recessive traits are supposed to have been phased out by the time of ME1, so brown/black hair and brown eyes are the norm, which is evident in most of the in-game human models. I usually give my femsheps brown hair, slightly tan skin(depending on background) and brown or slightly blue eyes, which are usually also the most natural-looking colors allowed by the character creators. The scars from ME2 and onwards are mostly enough to really distinguish Shepard, even if they're faint.

For the creation of V Shepard I used a lot more, obviously: As an example, this is a large part of the change-log used for ME3 Jane Shepard: 753.M1G.114.P1E.FL1.14S.BWH.461.KC6.573.2G6.27B. An AU where twins, John and Jane Shepard, face the Reaper threat together. Spanning the course of all three games, DLCs, and a few comics. Female Shepard (Mass.

If you want to recreate your ME1 character from scratch in ME2 by converting slider values into a ME2 face code, here's how to do it. It's very simple, but you need to know what the slider values were for your ME1 character.

CONVERSION TABLE:

Slider Value: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34
Face Code Value: 1 2 3 4 5 6 7 8 9 A B C D E F G H I J K L M N O P R S T U V W X Y Z

Example:

Below are the slider values and the corresponding face code values according to the conversion table given above. Note that * is the value for the scar slider which isn't supported in ME2.

7 5 3 11 || 31 12 16 16 1 12 12 || 1 10 15 16 16 1 1 || 20 1 1 10 || 10 1 1 16 16 || 6 5 11 || 4 9 16 4 || 6 1 6

7 5 3 * || W C G G 1 C C || 1 A F G G 1 1 || K 1 1 A || A 1 1 G G || 6 5 B || 4 9 G 4 || 6 1 6

Now let's put all these values into groups of three and add a dot between each group in order to form the face code, ignoring the value for the scar slider (*)...

ME2 Face Code: 753.WCG.G1C.C1A.FGG.11K.11A.A11.GG6.5B4.9G4.616

Here's how it looks like in ME2:

PS. If you want to get ME1 slider values from a ME2 face code (i.e. the opposite of the method described here) you can use this tool here.
