Not to be a nitpicker...but if youre doin an SS uniform the officers cap is wrong. You have her wearing a Wehrmacht officers cap in black. An SS officers cap should have the SS eagle and the skull and crossbones. Just a slight detail but figured you should know.
Coolness. Her smile, proportions and skin tone is really nice. You're great at pinups and should definitely do more! What about a series of pin ups for every nation that was at war in the era? THAT would be awesome.
The fact she wears a German uniform is especially awesome, because there are plenty of American pin ups, but no German ones although the German uniforms look way better in my opinion.
