I do find the girl animations generally to be overdone. I would rather just see a neutral walk with a few differences between the males and females, sort of a... wandering around the mall walk. I want a walk devoid of personality.
I want armour that is slick but looks and feels like armour. I want my character protected, no boob or midriff windows (not that I think they'd do this) and I do not want pink armour. I always hate seeing Ashley in ME1 in that glaring white and pink armour - have you never heard of camouflage, ******?
As for hair, I want a couple up-do or braided styles, not just the one bun. I personally don't like the longer chin length options because I don't feel they're military enough for my character, and I'm not a fan of short hair.
*These are all just my personal opinions; I understand you may play your characters completely differently from me.
Neutral style walk would be fantastic. The only thing I'm worried about is a female PC who swings her arms way out around her torso. Different sitting animations would be good too, but I'm trying not to be too particular. I just want a character that walks in a way that doesn't look really bizarre.
I differ from you on the armor coloration, but only insofar as I'd like to pick it freely. I just a color wheel, so that I could go with jet black if it suits the character and my mood.
But I'd also be thrilled with the option to go with pale lilac, deep crimson, or dusty rose if I please. I don't want anything too different from the ME2/ME3 armor color options, just with a little more precise control over shade and hue.
As for the military thing, are we sure we're definitely playing another military character? Since we found out the N7 figure in the preview isn't the PC, I've been holding out hope that we might be something outside of the human armed forces.
It wouldn't break my heart or anything if I'm wrong, but I'd rather not have too close a repeat of Shepard's story.
Totally agree with your on the hair part, they're should be a lot more variety.
With regards to armour though I have, I heavily prefer utilitarian and practical over style and sleekness.
below are some, admittedly rather extreme examples of how I like to see armor done in Sci-Fi, quite militaristic yes, but then again our protaganist will most likely have a certain affinity with military yet again.


Wow. We have absolutely opposite taste in armor. 
I really hope there are multiple options.
