I took some pictures of my kids (just snaps, wasn't a planned shoot or anything) climbing trees the other day, and I was struggling with the processing because it seemed like the red was always blown on part of their skin, but when I would try to correct WB in RAW first, they looked green or cyan. So I'm not sure how I did with these, ultimately, and what to do in a situation like that. Seems to me that I often have this problem with shady areas; red channel is blown slightly and nothing looks right when I try to fix that. (I know you can decrease exposure, but then it just looks too dark!)
Other processing feedback is welcome. I'm trying to get better with processing and finding it a big challenge.
I can't really comment on colour since I know my monitors colour is off, sorry. I think your composition is great and they are fun shots, the only thing that sticks out to me is the tree (bush) in the last picture cropping off his hand.
