i don't like that huge blob in the corner, and the frog is too pale in the background, over exposed, there is too many distractions in there. if you ever have doubts, follow them. when you see this frog in the future, try to get it without the grass in the way, and go for a lower exposure or use a polarizer to remove the glare from its back (the second option is better). when the main subject takes up only 50% of the image, the other 50% should be neutral, and in this case it isn't. even in black and white, the grass would stick out in all directions.
