As the police officer says in ME2 says "nice guns try not to use them in my district."
Let's hope Bioware take a look at some of the one's you've posted or at least consider using Ashley/Miranda as inspirations on how to do it and give those options to the player. Also with those free MMO's there's plenty out there to give Bioware ideas on how to do better.

Do it better?.. Yes!!
I fear, however, that the FB3 engine is unsuited for long hair 'cause according to Mike Laidlaw (DA:I) it causes clipping. So, it's either the engine or the amateur that was given the task of implementing hair styles or (and this may be a stretch) Bio ran out of time and the hair style assignment was changed to "slap on some hair options and make it quick".
If it's the engine, I expect ME:A to come out with short or relative short hair. Also, I fervently hope that Bio will come to their senses and omit those awful facial options from DA:I. If it's not the engine, then Bio can take their time to provide us with acceptable human styles.
Oh, and regardless of style, I want hair that looks like hair and not a barbie Ken type plastic crapola. After all, Bio has come out and gushed with glee how the FB3 engine rendered graphics look much, much better now that Bio is unfettered with the new gen hardware.
