This just isn't an interesting subject or composition, in my opinion. I'm unsure what the intended focal point was meant to be. If there was something about this scene that captivated your imagination, it hasn't been clearly communicated to me by this photo.
I have to assume you are going for the brown because this is the worst photo I've seen in a long time :) I'm sure you know that already so I won't point out the bad points. I'll try to find a few good things instead. hmmm Green is nice :) Uh, I like how the jug is off center. Thats about it LOL
I'm so sorry, I almost never say this, but there is nothing in this photo that I find appealing at all. I'm not sure if this is a case of selective desat, (which I am not opposed to), or just weird colors, but I just don't like it. I can't even determine what the actual subject is, or what those green things are. The only suggestion I could possibly make to improve this photo is to suggest that you take a different one. Sorry.
