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.
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:
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.

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: Micromax bolt a069 software update.

PS. If you want to get ME1 slider values from a ME2 face code (i.e. Panasonic kx tem824 programming manual. the opposite of the method described here) you can use this tool here.
