1. This is my favorite of the lot. The sign really stands out and is contrasted nicely with its background. The bokeh is nice IMHO.
2. This is nice and a runner up to #1. Although the background has a nice blur to it, the subject itself seems blurred too. The reeds have more focus.
3. I think that if you would have focused just a little more to the right you would have had a the entire fence line stand out more.
4. I'm not sure where you were going with this photograph, but its cool.
5. I like how the flames have been captured. A different perspective would have been interesting to see. For example, see the flames from the same plane as the grill.
6. The sun blots out the picture. Unless you're going for some sort of commentary on how man is ruining nature, I would crop out the tire tracks in the sand.
