Viriathus pinup sketches

This month's pinup is Vi from Dreamkeepers, and a number of the suggestions and info given to me by you guys had her as a tomboy, confident, with a big gun type. So I went off of that and  did a few poses ranging from more typical pinup style, to something a touch more unique and closer with parts of some. I'd like to hear back from you guys!

Also, I definitely need a better reference of this gun thing. And ideas for setting/lighting and such.
