There are a couple of things I like about your photo. First is that it only has 1 prominent flower type. Most of the flower pictures I've taken in AZ and CA over the last couple of months show multiple flower colors and shapes which seemed to be too much eye candy (too many things to look at). The other thing that works for me is the uphill perspective. It really allowed you to fill the frame with grass and lupines. The only thing I might try differently would be to move the tree a bit off-center if possible. Nice shot, though. Thanks for sharing.
Thanks, I took one with the rule of thirds tree also. Here it is.
Best,
