So what exactly IS pillow shading, I think I get the gist of it but I don't know exactly what it is.
And sure, I will try to make some trees like yours Wizzrobe, It probobly won't be too hard. Just time consuming.
Shading
With our light source firmly established, we can finally shade our object, starting with the simple example of a sphere. But first, an example of what not to do :
This called 'pillow shading', a great evil spoken of by pixel artists in hushed tones. It is the work of the devil, and appears to assume a single point light source hanging directly between us and our object.
Do not, under any circumstances, shade a shape this - it looks rubbish. This sort of radial tone gradient is suitable only for a surface lit by a very close light source - like the burning torches above.
