Its all coloured using Corel Painter except the black & whites which were marker rendered. And the only photoshop I use in my drawings if to give an extra glow to bright areas. And dude, give up? Why?? I have been drawing for 14 years now and I am still now satisfied with my drawing whever I compare it to professionals and that makes me practice even harder What I know is you need to have a basic understanding on tonal differences and shading. If you are good at that, it can make any drawing no matter how simple to stand out. Check out Ashley Wood's art. A sketch and loose style of drawing but he knows how to use tones and shades.
