Cute photo and a good concept, but there are a few flaws that kept you from getting a higher score. First, the lighting is not very good, you need more of it. It looks like you just used the existing light in the room? If you don’t have lighting equipment, you can use the on-board flash with good results, just be sure to turn it down to it’s lowest setting and/or diffuse it somehow (I’ve heard of people putting a piece of semi clear tape over the flash to diffuse it).
Also, for a portrait like this I shouldn’t be able to see all the wrinkles/creases/details in the backdrop. I don’t know if your camera has manual settings, but if it does you would want to set the aperture as low as it goes to get a nice shallow depth of field. This will blur the background. You can also set your dog up further from the background to blur it more.
The photo looks a little soft as well, that may be because of your camera, a slow shutter speed (because of the low lighting) or it just needs to be sharpened.
Again, great concept (a similar shot took second place) but it needs a little work. Great dog by the way, it’s either very patient or very well trained to sit there like that. Good luck on future challenges.
Fitting for the challenge and there is definite potential in this shot. However, I feel that for a shot like this to work, there needs to be some better details captured. This could have been helped by better lighting perhaps. JMO.
