Wow, Chuck, you read my mind! I almost started this very same thread, but decided against it since I had already started the other one...didn't want to be board hog.

Glad you did this!
In general, I won't vote for any photo that has bad focus, poor exposure, or is over-sharpened or has obvious photoshopping, no matter how good it might have been otherwise. I look for something unusual as well, not just the run of the mill cute kitty or nice sunset or mountain vista...too many of those already.
For example, here is a mountain scene I do think is different and very artistic:

And this one is good in my opinion because of the path which makes you long to walk down it...really draws you in:

And I don't find many portraits or candids to be interesting unless the faces and setting appear to have a story to tell. This is an example of one that I do think is excellent:

And here is another great candid...it has a lot of technical elements which make it good, including color and composition, but it also strikes the emotions and shows the essence of childhood in one shot:

Speaking of good composition and compatible colors, this one struck me as excellent because it wasn't a naturally beautiful scene...the photographer found the right place and moment to make a basement beautiful. Contrary to some comments left beneath it, the industrial light and railing add to the image for me, don't distract, because they tell what this place really is, which makes it all the more amazing:

Here is another example of making art from the mundane:

Animal pics are a dime a dozen so I look for that special something, like in this great shot:

...as is this one by Elizabeth Glass, though lacking some of the technical perfection of the first (the color is a bit bluish):

Basically, what I look for is something different from run-of-the-mill, good composition, good cropping, good color and tone, an artistic view of something mundane and not considered beautiful or interesting on its own.
I do not vote for photos of scenes, no matter how beautiful they may be, that are merely there for the shooting. A gorgeous garden or lake or mountain vista is already a work of "art" ...naturally. It's too easy to take a record snapshot of it and get a beautiful photograph. Nice to look at, but not a great photo to me. If you want a great photo of an already great scene, try an unusual angle, or stormy weather instead of pretty sunshine, etc... then you might have a great photo.
Boy, I could go on forever. But I'll let someone else talk for a bit.
