Greetings, and welcome!
#1; having only one figure in red isn't doing what you probably hoped for. If there were several figures with something red, it might have been the place for selective color. Many of us have something of an aversion for selective color due primarily to its heavy-handed treatment.
#2; Not getting anything in that one.
#3; The analogous color scheme is interesting, but I think a better composition to start with would have given you something more to work with and possibly yield a better result.
