Hi Raid....first of all, I enjoyed the set.
Regarding your concerns, others here have a better eye than I do for processing. The things I typically look for are pretty good in your shots. I can see a bit of noise in a few, but you seemed to have been able to correct that in the shot where it was most significant. While I agree with Bill, you may want to consider upgrading to LR5, overall your RAW-JPG converter seems to be ok to me.
But two comments that may or may not be related to your concerns
- From the lighting I am guessing these were taken ~1-2 hrs before or after noon. Working in that lighting can be tough. While the "magic hour" gets a lot of attention, some of my favorite lighting are actually from 2-3 hrs before sunset or after sunrise or on cloudy days. I am often disappointed when I think I have an amazing shot taken from around noon on a bright sunny day. So much contrast, so much DR, they often don't work out well.
- As you mentioned sharpness, you may want to check the AFMA on your lens combo. I could be wrong, but I assume you were focusing on the faces. If so, there could be a slight back focusing issue as it looks to me that 3-4 of the shots the bodies are sharper than the subject's face.
As I said, I enjoyed the set and if nothing else, enjoy the heat. Bill and I live about 30 minutes apart, so we are both in for the same 8-12 inches of snow and -4 F (-20 C) temps tonight.
Thanks,
Brant
