Haha yea I quite like the concept of a main base body of colour, like a more or less, then I just choose a direction of light and start dividing the hue of the are and shaping the main areas with various gradients of colour and then use more of a solid brush for highlights... I still want to experiment with more of that, but the areas of light and dark also add rad mood to the sketch... for this one I also tried to maintain some of the linework otherwise the whole painting just looks a little too soft? I dunno, its an interesting process :)
