Does any body think this is poor image quality?

Looks like an HDR image. http://bestsmileys.com/clueless/4.gif

Good call, Jim! Doesn't look natural.

High Dynmaic Range.

Or, you really worked the shadow/highlights tool in photoshop. Something about the lighting just looks that way.

HDR = high dynamic range

It's a technique for dealing with a shot where the darks and the lights are too far apart in brightness. For example, a fairly bright sky but no light on the engine. One ends up making two separate image, one exposed for the sky and one for the engine, and then merging the two. A much limited version of the same effect can be achieved through use of a shadow/highlight tool on a single image. Both techniques can be done to good or poor effect. Here, the shot does not look natural.

Poor Image Quality?
 
In one word: yes.

Here's the problem. Aside from the terrible color cast, this shot looks like it could have benefitted from sun on the subject. If you've got blue sky, you should have sunlight on your subject. Subjects shot under "blue-sky-cloud-over-sun" conditions all suffer from distorted colors because there is a fundamental white balance conflict between the sunlit clouds and the subject, which is overly blue from reflected skylight. Otherwise, the shot is sharp and level. There's way to much sky, but that's nothing that can't be fixed in Photoshop.

there's not much that can be done for this type of light. When I encounter this situation, I find something constructive to occupy my time like visiting the zoo. Got to see a beaver at the Bear Mountain State Park's zoo last week. I get my camera out again when the sun stops playing peek-a-boo with the clouds.
