It is a nice photo. I too like the texture. I think the junction box is totally fine - it adds some interest when looking closer at the photo, but does not catch the eye at a quick glance. The photo looks really dark to me. How does the histogram look? I feel like the photo needs to be at least a half stop up on exposure, or maybe try increasing whites and highlights. Does this photo have a red filter on it? If not, a red filter could make the sky more dramatic while maintaining a minimalist feel.
LFG!
