I agree with those who spoke about a warm color. I am not crazy about your yellow-greens. I think for a child, they need to be more in line with the true green in the dino print. I would add the brick red color (almost like the color you chose for the background of the photos). I would also agree with those who think the blues are too grey. Again, you want more "true" colors to match the intensity of the colors in the blue dino print. This dino print is really adorable.
