It is a great start. Try getting the pets in focus as well. The wider focal range, the better the photo (not always true, but it is in this case).

This site has a great explanation of depth of field. Look at it and the try taking the picture again.

I'm not a photographer, but I love the picture! It is so cute!

u have a good eye, try slowing your shutter speed down. Keep up the good work

Actually I don't think depth of field (how much of the image from near to far is in focus) is an issue here. The pets are pretty much silhouetted with the backlighting and I'd like to see you try to shoot this two ways and see which image you prefer. One as a complete silhouette- do this by exposing for the light outside the window- you will have to get out of any auto mode to do this and your manual will be a help here. Then shoot it again, but this time exposing for the pets- the background will be over exposed or overly bright. Pets aren't always cooperative, but try to capture them when they are framed totally by the window or door to avoid the heavy black bar being positioned directly behind them. Have fun- that's what photography is all about.

Its not compelling, study up.

I love this photo, really ! (:
It has a warm feeling,and a good concept. Everything about it is nice, just a couple hints.
Keep the camera a bit more steady,
Or increase your shutter speed.
If you're working with a digital camera, mess around with your effects//modes//settings on screen,to give different effects, or tones. It can completely change a photo,and give it a change of mood. [be sure you have the manual, or know how to change it back,so you're not stuck or confused ! that happened to me): ]
