Looks great. I read the exif and it says you used f22. You will get a little more DOF with 22 but that lens is much sharper around f11-f16.

The 645D is a great camera.

Yeah, I agree, I tested the 55mm on a chart (the shame) and like most of the 645 lenses, they start to get diffraction limited from f/16. It looks every bit as sharp as f/11, but the moment you stop down more you get softness in the image,

In that particular image you can get away with having the DOF reach out only as far as that last tree on the right that is leaning inwards. This would help keep the main trees as sharp as possible. The eye will still be drawn in.

It's hard to judge but I have found that MF landscape is as much about managing dof as it is about other technique.
