It's not bad Julie. Slight overexposure, but that's because of the green I think. I read something about green likes to be underexposed by about 3/4 of a stop or so. It's a cool composition. The blue cast over the photo may have actually been there if there was diffuse light and not direct. Could have been a white balance thing too - maybe change to "cloudy" or "shade"? Circular polarizing filter would also help cut down the glare on the leaves (that blue sheen) and given a darker green.
