A fascinating, heart-warming pose of a lively, colorful lady. I liked the light a lot, enlighting the hat handsomely from the top, and yet the face traits are easily recognizable. The colors, blue and yellow arecolors that go very well "emsemble". The background is nicely blurred, I wonder whether you needed any extra processing at PS.
The location of the head is nice vertically, and the row's diagonal position is good, whereas my only nitpicking is the very central position of the model. Did you try a square format, or try to position her a little bit futher right?
Thanks for sharing.
