previously i've tried a sporadic dotting technique.
afterwhile i realized, why not increase the number of the dots of various sizes?
so i just tried, with pretty cool result.
i think this is higher level of dotting technique.
there's one thing i realized though,
i was trying to fill these dots all the way, but by doing so 3D effects will be erased.
all the dots of different sizes contribute to the 3D looks.
so the original chinkin method, i think work better with the dotting technique
