How goes the work on SSAO? Here is ready solution for GLScene:

My shader is very similar, but I added automatic change of size of ambient shadows and added fog.
The size of SSAO is dependent on the camera's distance to the observed object and the fog covers SSAO in the further view.

By the way, I made several improvements to the Depth of Field (blur was too strong) and now it looks perfect
