ok take this hastily-thrown-together example below... do you want it to be cartoony (such as this) or more realistic (which usually gets flamed more)
do you want more skin, as in terminator type, etc.
and please, ignore the crappy terminator t-600 decal, it was an experiment that went horribly wrong. i am just too lazy to pick another for the sake of an example to get an idea of what somebody wants.
