I like these old machines! I work now at a living history museum that uses them. Nice point of view--a classic one. It might be fun to try some new angles from which to shoot. There is a slight misty feel to this. You can try an Unsharp Mask with a large pixel radius and a low percentage and it will appear sharper. Nice work.
I think the subject begs for a little "head room," but, that aside, I find the image pleasantly composed. A low contrast also adds to the feeling of "age" and being "washed out" through time. Overall, I like the picture.
An elegant subject and nice shot. Pushing up the contrast levels will probably make it more impactful. Not sure if the noise is intentional ... Not sure it adds to the photo.
What a great old tractor this is! For some reason this seems cloudy, could it be improved with blacker blacks? Contrast, maybe? I like most everything about this (focus, dof, and of course the tractor) - just feel it's missing some zip which could be improved with stronger tones possibly.
