I'm gonna chime in with a gotta keep the bench. Landscapes are hard because they all look the same. (In general, anyway). Everyone wants to take a picture of the pretty mountains, the pretty lake, the pretty ocean, the pretty whatever. The problem is, there's no variation, and it all looks the same. In the end, pictures of pretty mountains are just that, pictures of pretty mountains. We've all seen them, we all have pictures of them, and they are very forgettable.
When you are there taking the photograph, you have all of your senses working for you. You see the scene. You smell the fresh mountain air, and the wildflowers blooming. You hear the birds of prey calling out, and the sound of the song birds in the bushes. You feel the crisp mountain breeze on your skin. A photograph only engages 1 sense. You are trying to capture a scene that, for you, was utilizing 4 or even 5 senses and somehow conveying that to your viewer. You want them to be able to imagine all of those things you actually experienced. Not to mention, landcapes are 3 dimensional, even though most "snapshot" landscapes are very 2 dimensional. You must remember that you at the very least, should have a foreground, and a background. Most good landscapes have a "midground" in there as well. Your eyes should move throughout the scene to find a bunch of different aspects. I've heard of landscapes being best described as an interesting foreground object with an amazing background.
Using that as our "landscape mantra," without the chair, all you have is pretty mountains (eh...) and a lake. The chair has character. It gives a point of focus. It helps to tell a story. The chair should be featured. It's the rockstart, and the mountains are just the backup dancers, if you want to use that kind of analogy. Having said all that, I do believe the image suffers from some other problems. The ground in the foreground is ugly. The point of view was taken from an averageish height human (likely between 5 and 6 feet). Shooting from a lower angle, maybe closer to the bench, could potentially make for an amazing shot. Although the sun isn't overpowering the scene (might have been behind a cloud or something), the time of day isn't very conducive to this type of shot. Waiting until the sun was low in the sky would have added a lot of drama to the scene.
I have a passion for good landscapes, and I have been trying my best to take great landscapes ever since I picked up a camera. This was a great attempt, and I applaud the OP for actually adding a forground element, where most people would have left it out, or forgotten about it.
