TL;DR:
Software used - SketchBook Pro
Went for a very rough painting style with this one. Tried some techniques frequently used by WLOP. No custom brushes were used for this artwork. Sketching and coloring all done on my 5.1 inch screen Galaxy S5 Duos device in SketchBook Pro (Pre-loaded brushes, call them whatever you want). For anyone new to my profile, I draw all my artwork without a stylus on my phone screen using my index finger.
Also, first of my works that is easily readable from thumbnail view so I am pretty proud of what I ended up with!
