#1 has shadowed the subject's face too much. maybe some reflector?
posing is fine for a newbie.
can check out some good portraits for examples in achieving the art-pose-feel.
but i think the colours are something quite refreshing. that's artistic.
a working model would know how to pose naturally for the camera with little coaxing.
the gal here looks like she's doing fine posing for these few snaps.
the chemistry between the photographer and the subject (gal) will be enhanced if you are both comfortable w each other
and can be achieved w more shoots. hey, it's good chance to ask her out for more shooting!
the makeup is... uh... self done right? the eyeliner is like...not precise. work w some practice or else get the bobby brown counter service prior to the shooting session. it's quite affordable and the staff are usually friendly and can provide good help.
