I'm another who doesn't pay much attention to the rules, although they really are a good guide. Of course, some of my renders suffer for that. I just go by eye, think it's more fun that way. To me, this scene isn't a matter of lines, but one of interest. I don't mean to say your subject isn't interesting, far from it. Dead trees on a flat plain can make for a fascinting picture. It's all in how you approach it. This is just my own taste speaking, but I'd lose the left 1/3 of the scene. There's just nothing happening there. If you don't want to do that, add something that spans the scene. Also, the terrain is extremely flat. I've been to some flat places in the world, but there's always some amount of bumpiness. A few boulders would add interest beyond the dead trees. Maybe a vulture circling around overhead. Even on a flat plain like this, I would expect to see some very distant mountains. Make em extremely low, and fade out a lot. I think lighting is the most important thing to consider. The sun appears to be ahead, just to the right. A very good position. But the trees are lit from behind the camera. Try letting the sun light the scene. Lots of shadow could make your subject very dramatic. I could be wrong, of course, but give it a try. I'm really interested in seeing what happens when you try some of the suggestions here. Be sure to post an update.
