First impressions:
1) I like this one, although I might be tempted to crop it a little closer and put the flower in the centre of the image- one time you can chuck the rule of thirds.
Didn't because I wanted to get those background tones.
2) This one is also interesting, although it would be a bit better with a more symmetrical arrangement. I like the chairs - it adds to the "nobody" theme - everyone left and there is no one home. It would also be a good image without the chairs.
3) Looks more like an environmental disaster!

I like this one, not sure why, but it has certain abstract/randomness appeal to it, for me anyway. I would be curious to know the circumstances of how this "mess" came about.
It's the place where my brother in law does clay pigeon shooting.
