This has a nice effect. The only thing you need to do with the effect is erase the rays of light from in front of the plant. The light is behind the palnt so the plant would be blocking them out.
I agree that I like the size of these as they are but I'm bothered by the plant going straight up the middle of the image. I would crop this from the right side a bit to bring the plant and frogs over to the right frame.
It's got potential.
