I made this comptest by using real rendered passes. It is alright as an image. But when the camera is moving, the ground's edges start to blink. I think that there might be some rendering problem. I have been attempting to solve it during this weekend, but will use it anyway when the composite process starts. :(
As you may notice, this version is a little darker, and have higher contrast. Its depth of field has been increase slightly too. I have got about 80% of passes sitting in the render farm now.
