Not bad Frei.....here is a paint-over with some areas that I feel need some work....mostly I concerned myself with the pistol and holster because quite frankly...she looks good otherwise. My biggest non- technical observation is... what is she looking at? Because neither gun is pointing in the direction she is looking in....not that they have to be....but it makes me wonder how she would hit anything if she's not even looking at a target.

Okay....the red lines show how the guns should be sitting....guns are generally made to follow a natural pointing of the index finger, while some do this better than others...it is the common goal to make it point naturally in the hand when held properly. They also are designed with the barrel sitting as close to the line made by the index finger as is possible...meaning the barrel is sitting beside and slightly above the finger when it is out-stretched and pointing. There is actually a reason for this design....it helps reduce the amount of recoil felt and maintain control over the pistol when fired. Basically the gun in her left hand should follow where her hand is pointing more. The gun in her right hand should have less of the side visible to us....and though I didn't mark it ...the barrel should be closer to her trigger finger. We should also see more of her thumb here since she is still holding onto something and not simply making a fist.
The Blue line is just showing the direction her finger is pointing in more-or-less.
Okay, now for the holster....something I know a thing or two about. Holsters are a designed to carry a pistol on your person in such a way as to make it quick and easy for you to draw and fire while also keeping the gun protected somewhat from being damaged and made unusable. There are many designs possible and are often a reflection of a particular preference of the wearer to to grab their gun(s) in a particular way. However there are certain things that MUST be considered for nearly any holster.
1) The holster must allow a proper grip on the gun before removing it from the holster. Fingers wrapped around the grip completely.
2) It must allow you to return the gun to the holster with one hand. Many holster don't do this but for reasons that I won't go in to.....
3) If your going to be leaping around it needs a strap to keep it in place. Modern technology allows for other ways of keeping it inside....but the old fashioned way was a strap across the hammer....or back of the gun. Usually a thumb-break strap which allows you to release it as you grip the gun and then pull it free. The big exclaimation mark is to say that the strap across what's called the backstrap of the gun is a bad idea....it interferes with gripping the gun properly and can prevent you from drawing it out quickly.
In reality your first holster design was quite sound.....just Google Glock and browse their "accessories"....not too different at all. I liked it myself. Especially take a look at their "Safety Holster" and you will see what I mean by other ways to keep it inside.
Oh and I agree with Fav.....her butt needs some re-shaping in the cheek area.
Love the face....looking forward to seeing this done
