I recently got a few sets of actions to play around with... I got the Totally Rad Actions 2: The Revenge (TRA2) and they are nice... but my favorite so far is Florabella Collection. The new line, Luxe, is my absolute favorite and I've been having a blast playing around with the different sets and actions (I purchased the whole collection... all 6 sets of actions plus 2 sets of textures).
I love this picture of Hudson from Lake Michigan. I was playing around with different actions and couldn't decide which one I liked the best. I thought a little comparison would be fun! Which is your favorite?
