Last one is the best in my view, smaller stream, disappears in the distance, foam in appropriate areas, decent downslope/waterfall. I say keep the yellow flowers. The whole thing looks noisy or perhaps oversharpened though. To my eye it'd be better with either higher AA, higher detail, a smoother AA filter, or just not doing post work sharpening, depending on which of those apply. If post sharpening is being applied in any way, that's almost certainly the culprit. But as usual with these things, individual taste varies...
