I tried to create some portraits of my daughters

The adjustment brush (which you should have come across after 12 hours of video) - let's you 'paint in' adjustments on particular areas of the image.
Shot 1 is best so far in the new edits, but it still looks red to me.....and you didn't follow the advice. You didn't outline your steps...
and I see other programs at work here...and I'm just gonna say it... a child imo, doesn't need an airbrushed look.
You children are gorgeous AT. Both could be models. The airbrush (especially in new edit #2) makes them look UNchildlike, like they had too much plastic surgery or something.

I can't comment further on these images until I see a natural one using only LR and outlined steps.
