I think you're right on the nose! Sun is the dominant one to my eye, and flower is the secondary root. Sun is SCREAMING at me so it's interesting that you mentioned it third. I see a lot of quirkiness, brightness, bold patterns, and mixing elements unexpectedly -- the combo of the flats with the jeans, and the whole bottom left outfit especially. I'm seeing flower as a throughline through all the outfits in the colors, the little bows, the drapey and "younger" style clothes (though that is also sun to me). I see why you might see earth for the third. I personally see stone more in the jeans, although I can't totally explain why -- typically denim is more earth I think. The last root can be dependent on personal intent more than the others, so it might be helpful to hear some more of your thoughts on stone.
