About post processing...



Ok, I have taken some pictures with my new camera, and I have Lightroom 4, which I'm trying to learn. I've been using photo editing programs before now, but not like this one and I've not done much more than crop a bit and apply the auto enhance. So my question is, if you don't mind giving me some feedback, what should I be doing in LR with these images? (I couldn't get the raw images up here, so these are JPGs).

In the portrait, should I try and make the face lighter? Is the interior fine the way it is, or are the colors supposed to be more saturated? Is the truck supposed to be more saturated? I guess the sunsets are the ones I'm struggling most with. Am I supposed to have more detail in the mountains, or what? Should I be working with shadows? I need some direction. Please.

Thanks, Denise
