Aww, he's pretty happy there. Great shot. I would get rid of most of the back wall, its distracting to see the knobs and the color doesn't complement your subject well. Try to zoom in and catch that face more, Hes a cutie!
OK - pets, kids and toys, unless they are especially good then they tend to look like snaps. This has very obious 'snap' giveaways - the dark shadow from onboard flash, the taps half in frame and half out of frame, the sloping and very plain background.
Now, for an example of how good kid photos can be go and check out some of Jacko's images. He used directional light either from an off camera flash or from a natural light source (window). He makes sure that the background and setting do not distract from the baby. Well worth studying some of these techniques.
pretty effects of light in the water. cute child. strategic placement of the rubber duckie. would like to see this image with some light bounced from the other direction to add some depth and knock down that distracting shadow...plus a little bit of cropping on the right. adorable expression!
He looks like a happy baby! I think the picture could be improved if you were able to bounce the flash to eliminate the shadow on the left of his head. I would also have cropped the top 10% off to eliminate the fixtures. Great looking baby!!
Different lighting, a different angle, or a different composition (closer, perhaps) would make this more than a baby snap-shot. If you could get an assistant, a light shinging from behind (above or from the baby's right side and behind) would add a third dimension.
