I like the apple picture and the leaves
I was looking for some photos of autumn leaves with a white background a few weeks ago. These would have been fantastic!
I quite often want flat/overhead images because they rotate nicely. Photos taken at an angle which have an obvious "top edge" to them, like your tin cans are more difficult to use because they can't be rotated.
In a game, an apple might be rolling, or the leaves turning as they fall. So rotatable is something I'm often looking for.
Good luck with your wordpress blog, and I hope to see more images in your gallery in time.
