Hey Steve, I'm the opposite of you. I'm into photography but I can't wait to start learning some video -in the distant future when I buy a camera that supports it-. I'll try and keep the feedback appropriate for your said experience.
#1:Capture wise it's hard to say, it's just not that exciting really. You've just gotta work on that over time I guess, I can't think of how I can help with that. I just look at photographers I like and it will come with experience.
Processing seems weird, too much clarity or unsharp mask. Or maybe you've selected everything but the sky and tried to drag down the brightness of it and the selection just isn't ideal. If you turn on image editing I'll have a go at it -same with your 2nd one- and see if I can give you any pointers as far as that goes.
#2: Same sort of comment for the capture part as number one.
Did you do that selective correct white balance thing?
