Hi Travis and welcome the forum! I am not sure if you are aware there are a couple of places to get comments on your shots - one is specifically for critiques in fact
Here
I think this was set up as a result of the forum growing and people posting pictures and asking for suggestions on improvement (instead of the standard I like it , nice capture. etc).
The other couple of areas people use is the
Post your Photos asking for commnets and
Post processing asking for post processing tips.
I do like the idea of a signle theme however and a signle place to ask for help and or suggestions. We have some great photographers here as well as many wizzards at post processing (of which I am neither haha)
I think these types of threads probably belong in the
Phot Critique . The title can be monthly theme with the understanding people are looking for comments on what camera settings , framing post processing, tips, tricks , etc could have been done to make the picture better.
I for one would participate in such an activity - not so much a contest unless at the end you declare some sort of winner
my $0.02.......
