I like the compositions in all of them. The group of three works well in the first one. Perhaps I should also participate in these themed weekday shoots. Less trouble to come up with a theme. By focusing on something specific might allow one to learn faster.
I certainly invite you to #MonochromeMonday, #TreeTuesday and #SepiaSaturday as these are the ones I host. My good friend @dswigle hosts #marketfriday and @keithboone hosts #featheredFriday
