Cute kids, don't know why the faces seem to have a shade, shows that you've used flash, should be a lot brighter, anyway like I said, cute kids and a nice image, pity about the fur in the right corner..
Good shot, little bit of shadow on background. Next time try lighting the background seperatly. Object in lower right hand corner is a little distracting and doesn't need to be there.
How sweet. Love those eyes and that hair. Wow. Not sure what that is in the foreground on the right (a step maybe), but maybe if you had zoomed in and cropped tighter on them, maybe even portrait not landscape, you could have gotten rid of that and still had a great image.
Very cute. I'd crop out the top part of the background above their heads and the lower part, so that you are just concentrating on their adorable faces. . Love the natural skin tones.
