Keep in mind that armor is metal and as such is extremely uncomfortable to wear.
Beneath suits of armor is always leather at the very least, and possibly chain on top of it and between the armor joints.
She looks like she's wearing a full metal miniskirt and tanktop which would be -extremely- hard to move in and uncomfortable.
Also, the angle that the sword is at, combined with the thinning toward the hilt make it look like the metal bit would end before the hilt begins. Also, since it is a two-handed sword, the grip should be two-handed as well. I would seriously suggest making it a constant width, or tapered toward the tip.
