Hi, as requested, here is an indepth critique of your submission.
First Impression - the most important one: It's a cute pet photo, but generally images of pets don't do well in challenges, unless they are super special.
Composition: It fills the frame, but that's about it. Nothing is strong about the composition.
Subject: Being that it fills the frame, subject is very clear. We know what we are looking at.
Technical (Color, focus, and light): Color: For Duotones to be effective, the shot must have been shot with the purpose of making the image duotoned. Not just taking a pic and duotoning it. The duotone doesn't really add any value to this shot.
Focus: Sharp and in focus.
Light: Good, relatively flat, but flattering.
To grow its vote?: As I stated in my opening, pet shots don't generally do well in challenges. Voters see them as an easy out, just to meet the challenge. Get out and have some fun with the camera, try new things. Have FUN!
Summary: I hope I don't come across as mean spiritted in this critique. I really don't intend for it to come across that way. But, I'm looking at your other work and you can do so much better than this photo.
That cropping of the tounge really disturbs me... first, I though someone had two fingers up the mouth of the dog! :| Still, there seems to be a little white spot in the middle bottom half, which my be the reason it was cropped so tightly.
I think pet pictures have to be really really special to get the good marks. This one appears a little washed out, grainy and the focus isn't really nailed. However, it did make me smile so I upped a point
