Your vehicle models are looking great, there looks to be some areas that need work on your female models though. The armpit area looks a bit odd to me. With regards to the nudity question I doubt anyone will have a problem with it.
I was considering making a demo reel so I am unsure about the texturing side of things although I think most places expect modelers to be able to lay out uvs and texture so would advise texturing your models if you can.

Good luck
