I suppose color is one of the major things I have doubts about. I’ve noticed that a lot of my color processing ends up somewhere around here (which, to myself, I just refer to as ‘brown’). Personally I like it, but I always wonder if others find it garish.
I tend to push my shots a bit “warm,” but what makes these seem a bit odd is the warm “golden hour” coloration while in shade. Unless you’re getting fill off a sand- or adobe-colored wall (or maybe even off something like bronze-glass building), I would stay away from using it in shaded shots.
