This is the stereotypical absurd nude female warrior who distracts her opponents with her cleavage. There was a direct inspiration for this drawing and it was actually a study (of sorts) of the following image: The Vampire by Elda.
As you can see the pose and some of the outlines are the same, I also had no background at all but focused the image on the character itself.
Initial pencil sketch was very quick and much more in tune with the original drawing by Elda, I then scanned and took some liberties with the character including the nudity. Probably 1.5 hours total spent on this. I was working really dark in Photoshop and at the end used some tricks to increase contrast and the ink outlines are a simple PS filter – I actually liked the look of it and layered it on top of my main sketch. Cheers!
