To be honest, I don't see much yellow or how yellow leads to the impact.. the part that's supposed to be yellow looks a little green.. hmm my monitor looks calibrated, but still i don't see how its yellow.
As for the shot : good capture.. I would like to see a little more sharpness in the bud..somehow it looks a little smudged...did you crop too much ? It has some noise on the left/bottom corner which you might like to reduce. the lighting is good. Overall 6
