shading in real life

I agree, it looks extremely good! The shading has slightly obscured the lineart, giving it that mysterious feeling of the third dimension once more! Also, I must admit I like the way the certain shades are stronger than the others, creating a more shadow-y feel to certain areas, thus highlighting others and thus creating a feel of togetherness and a feel of one-direction light coming from the upper left corner. One-direction light is a tricky one (at least for me ) so that's really well done
