Once again I find myself wanting to make the same comment as Ron. 5 & 7 are my picks also. You may want to run some noise reduction on the backgrounds of these
You can get some plugins for noise reduction in photoshop and or lightroom that give you a bit more selective noise reduction options.
There are several, Noise Ninja , Nik Define 2.0 and Topaz DeNoise to name just a few. These are not free, but you may wish to look into them and try a trial version.
Thanks for all the nice comments! I will work on the noise reduction tips. My knee surgery went well, so I am going to have some extra time on my hands to work on editing skills.
