What do you think of this photo?

Composition is fine to me, not everything has to follow the rule of thirds, because that would be boring.* Good separation of the subject from the background, any less and it'd be distracting, any more and the scene wouldn't be recognizable as a field. I dig the low contrast, washed colors. Focus is good, exposure works, horizon is a bit tilted: Congratulations, your photograph is generally technically sound.

But critiques ought to go past technical aspects, though that's hard to do unless I know more about you as a photographer. I believe that you conveyed your vision for this photograph successfully, meaning it turned out how you wanted it to turn out. Emotionally, I have to admit that I found it funny, but not in a bad way. I had a horse that would always walk around with a piece of grass hanging out his mouth just like that, so when I saw the photo I audibly laughed. Otherwise, your subject's expression, hair, and younger face mixed with the piercings and military-style jacket conveys a confusion of innocence and lack thereof. This works well. The grass shoot adds a country simplicity. If you're telling a story, I see a girl who's probably at that age where she's causing her parents all sorts of grief as she's discovering a burgeoning sense independence, but still remains a kind hearted young woman. This is something with which most of your audience can sympathize. Or I could be completely off, as we all interpret photography based on our own vision of the world. You did well, thanks for sharing.

*In this shot, I think a centered composition would actually be superior to using the rule of thirds. It adds a simplicity, makes it look more realistic and less intentionally photographed. I believe your subject with the composition.

Looks good. I think the composition is fine. As it is, it doesn't need to be in the rule of thirds.

What I think could be better is the vacant, empty look in her eyes. She looks dazed. What I would do in these situations is ask the model to look at an object behind me, like a tree, flower, or a person, just to get her eyes to focus on something.

Or conversely, have her look straight at the camera.

Also, that stick in her mouth is much too large. I would've gone with a thinner blade of grass.

That's pretty good, actually. I might've placed her on the left or right rule of thirds line, I'm not much a fan of positioning her in the center of the photo. Also, maybe adjust the levels and curves on Photoshop to give it more contrast? It's slightly flat as is, unless that's the look you were going for. Overall, nice photo!

The horizon is tilting to the right. It makes me feel like I'm sliding with it. Oh well, I'm partial against piercings too so maybe that's why. Exposure is great, DOF is spot on, but you will have to learn more about composition.

Either going for a rule of thirds position or a tighter and closer framing. The image itself is good and the background is out of focus and not distracting or anything.
