the theme should now start to show some kind of cohesion. I hope that all would view each photo as a part rather than a whole. I really don't know where this is going to lead to, perhaps, confusion. I'll see.
Kind of primitive with an interesting sense of symmetrical design. Three trees = Feng Shui. I really like that wonderful bluish tint that comes out of the branches! Curious to see what you do next ;-)
I'm quite enjoying your excursion - you're doing just fine with your theme and your various interpretations. Play on! It leads where it leads and that's half the fun.
Wow, I just LOVE The high contrast here! I'm a big fan of white skies, actually, so this is right up my alley, but what is very cool is the purplish cast to the trees, wow again! And a great arrangment of trees.
