Looks nice overall. It seems a little busy maybe. I'd talk more about the owners, it's a great pic and you're a big selling point. People are buying you as much as anything.
I'd swap the pics of the kid and the dog, put the kid on the front panel and drop the background image behind the pooch. The kid does a better job of reinforcing the clean home/healthy home theme. I'd work in the kid safe/environmetally safe bit into the front panel, too. The dog is cute and makes for better humor, which is good, but with everything that's going on the background image is distracting. I'd use the free space over the pup's head for some limited text explaining the benefits like cleans deep, dries in hours not days, no sticky residues, stays cleaner longer, if spots return so do we, your absolute delight guaranteed, just a handful of what you think makes you stand out.
The inside is hard to see but I'd try to break up a bit. It feels little too much like a text book or something. Varying the layout makes it a more pleasing to the eye I think. Maybe fading out the background more and adding a few images of what you're cleaning.
