Hello, and welcome to my second Instructable! I will be showing you how I drew this picture, which I have entitled Emerald and Ebony.
This mostly just shows my drawing process, though I hope it can help teach people, as well.
I used GIMP, or rather, GIMP Paint Studio. GIMP can be downloaded for free from here.
The GIMP Paint Studio plugin can be downloaded here
. The same principles I use can be applied to other programs--the reason I use GIMP is because it's free. :)
