This is nice! I like that you converted it to black and white - it has just the right amount of highlights and shadows. Perfect!
I don't really understand why pet images are voted down, either. My theory, however is this: A lot of new users here may not really know exactly what to shoot. Then, "oh, my kitty cat!" and so they enter a shot that's not really all that great. So, perhaps the voters have seen so many not very good pet photos, they just autimatically give you a bad vote and move on without really looking at the photo. :( I've had that same problem... Photos of my cat that I REALLY liked were give an average or below average score.
AAAAHHHH. She is so cute. Just had to see who commented on my Lexie. Great to see another Shih Tzu owner. I have always been an admirer of B/W photos. This is a great B/W photo of Zoe. Shows alot of detail and expression. Very good DOF and nice crisp focus on the eyes.
I was glad to get this to critique. Not only is it a cute photo, I have very little I have to criticize!
I don't usually comment on score, but I'll say that this is underrated. This probably has more to do with subject bias than anything else. Kids, dogs, flowers. Some people just vote low and never look back.
Aesthetics: Very nice shot, cute subject, great head tilt. Composition is good except that you would have been better off with some space on the left and not cutting of his ear. A square crop is perfect for this--so you would need more space on the left and less on the right. More background blur or a simpler background would have been good, but it's not a major issue here.
Technical. Sharpness is excellent. Tones are generally very good. One issue is the area of overexposure/processing burnout on her head and a little possible burnout on her fur on the sides of her nose.
Nice shot, cute dog. What else is there to say! Hope what little I had to say critically is of some help.
