A couple of thoughts. First, as mentioned, too many photos. Not as though we, as a collective group, are unwilling to help, but we need to focus on just a few at a time.
So, as a whole, I say this. Your patients is there. You seem to be willing to wait for the right shot. This is crucial. Moving to an SLR provides so many advantages, albeit with accompanying challenges.
You have a great sense of what you want to photograph, but you just are not getting what you want. This will happen with SLR. You will be able to experiment with DOF (depth of field) to isolate subjects or includes additional subjects.
Also, even the most advance point-and-shoot will never give the full coverage of an SLR, with the exception of the Sigma DP1.
Pick a few you are most critical of and let us work with those. Then submit more. Photography is like the ocean, not a pool; it is not best to just jump in. Start at the beach and walk in.
