Okay, so earlier this year, I had drawn this very cyborg by hand.  Then, when I got Gimp, I decided to do some fancy lineart with the stroke path tool (since I am super OCD and I wanted it to be just right) , and then I colored it. 

P.S. I colored this using a drawing tool that I bought using a gift card that Phantom1880 gave me for my birthday. Thanks, Phantom1880!
