While you used selective colouring to highlight the caterpillar as the major subject of your photo, I would still suggest to also venture into some cropping to point it out more. The big dark leaf in on the left is quite overpowering. Selective colouring or not. It is just to big and too close NOT to be very powerful. You might leave the selective colouring as it is (his colour is too beautiful NOT to be shown :greenpbl: <- and if you know me well enough already you will now why I say so with the :greenpbl: added, it is more for the others who already begin to tease me for my love for this particular colour) --- and further consider a vertical crop of this photo.
