Nice work, but I just love the colour green to much (first thing you hear about me, eh?) to be wanting to miss out on it. And lighting of this one looks like the green might have been really pretty.
But yes, I must admit, the effect is there. The yellow really really stands out.
its great, although it think it would look even better if you had the flower the same but had green fading from it, not very much but just a tint of it
