COMPOSITION He looks like he didn't completely dig being wrapped in gauze! I think you should have filled the frame with the dog. The wide shot with the bed (table top?), bedpan, etc, doesn't really add anything to the shot. The dog, with very high cuteness factor, is the main attraction here so let's see more of him. Tighter on the face and eyes, maybe more detail in the gauze wrappings and pseudo cast on his legs, etc.
TECHNIQUE I don't think it's brightly enough lit, and the yellowish background is very unappealing. I wish there was more detail to his face and eyes. With 1/40th of a second, I wonder if you were struggling with the low light yourself. The details of his face are difficult to distinguish because everything is in such dark shades. Maybe by eliminating some of the lighter tones in the bed, you could have stretched more tonal range out of the face, showing some more of his personality? Easy for me to say, I haven't shot many dogs.
OVERALL IMPACT A cute dog with bandages, what could be more endearing? Somehow, you fell short of really pulling it off, IMO, though your score of nearly 5.9 is quite respectable. When I first glanced at your shot, it did elicit an "aaaaawww" from me, just because he's so darned cute. However, the full potential impact of this shot was not realized.
I think the pose, the look, and the idea here are very good. I'd like to see the colors adjusted a bit as the whole thing seems a bit faded. Perhaps that was your intention.
The lighting isn't the greatest, and the orange blanket (or whatever it is) is very distracting, but you know what - I don't care a bit! This is so cute, the look on that little face looks so pitiful that it just doesn't matter. Only the emotional reaction to it does - and it's adorable!
AWWW Love the dog and the bedpan and bandages. I'd remove the pillow with the pattern on it. Also, the orange and white quilt might be better if it were a solid color. Maybe if the whole thing were done in sepia and black and white. Nicely composed. The dog is a touch out of focus.
