Here is the same subject I did today: a female soldier holding a Remington MSR sniper rifle at the rooftop in the middle of the war zone. All done by using ink.
Here are the steps I followed. First, I found this picture on Pinterest. I started by doing a rough sketch of the body pose. Then, I began brainstorming how to make this painting.
Before moving to the actual painting, I'll sketch to see what it will be when I move to the final painting. Because I'm using ink for this painting, I want to be creative. The headband she wears, the ends I want to use, brush stroke to show how amazing the ink can do. The rifle is using a G pen with ink to outline, but the shades are brushes to paint.
