Hi Jessica,
This picture is more interesting to me than your previous offerings in that we have a context of a beautiful background that gives the dog an environment and so tells us more about it.
Again, you have a handsome subject. In the hands of a master printer, this would make a stunning print. What size file is this? Was it taken in RAW and what camera and lesn did you happen to use. The latter details are not important for the artistry of the picture but do impact on printing, perhaps.
You seem to like close cropped images. If it's your intention fine! That's O.K.
My presefence is for more of the background so that the tops of the trees are visible and also so that at least the eye can be seen and a tad more of the dog.
Photography teachers, priests and guru's advise to crop close then closer. Yes that's often admirable.
However, in learning, and especially today when in reality, we restart making the picture in front of the computer screen, wider is sometimes better. And why? Wider framing allows one to experiement and explore many different compositional options.
If you must be religious about close cropping when you press the shutter, do so. However, also take some wide angle shots. This will permit you to learn more about possible new choices for composition at the time of pressing the shitter.
The picture has the dog's head smack in the middle and that people don't like. However, I like the pointing of the head to the dog's right. Now if there was a lot of landscape there, it would be even more fascinating as it would appear that the dog is looking there and thinking about it.
The colors of the picture are particularly attractive. I cannot think of a more pleasing combination. You have a gentle blue sky, the layered hils in the distance, green grass with shadows and a dog with white fur like clouds and brown and golden fur like the mountains of landscapes. In fact, the shape of the dog's face is itself like a large mountain.
So, if this ia a place you can return too, I would. I can see you have now two excellent subjects.
Great and good luck.
Asher
