Okay, I see. Technically it's not bad, but the light and time of day conspired against you. You have deep shadow and bright highlights in the same part of the image. As mentioned, the crooped head of the seahorse is a bit distracting. I would take this back into post and try and reduc the highlights a little, brighten the shadows, a LITTLE bit, and try to increase the saturation on the grass. To be honest though, the message I get from this is not one of happiness; the way the merry go round is tilted makes me think 'abandoned' and 'disgarded'...
