one of my favorite things to do is go out and shoot walls here's my random thoughts you may find useful
I think you're on the right track. What I notice the most is that your proportions are a bit awkward. When you compose these take your time and look at the different textures,colors, and lines and see if you can 'balance' them all
like
>>3106243>>3106236>>3106315these in particular feel very unbalanced. What I like to do is try to divide up the areas in rough percentages and make sure there's not ever areas that take up too much weight of the photo
>>3106230this is a really neat wall to shoot but another very unbalanced shot with there being a lot of sky and the very uneven ground. This is a situation where the wall itself is a really interesting combination of constant unbroken lines, strong textures and colors. You'd want this to dominate the frame and putting it in the middle third just makes it sorta meh. Also mind how things line up. The white line being slightly off of those metal ventilation ducts and the odd placement of the other two ducts one being too close to the edge and the other just in an awkward spot really breaks it up for me. This is something you'd definitely want to reshoot though. It's a neat scene
>>3106263I'd also agree that you'd probably want to attain better tonality but you can do that as you get better at PP to really make what you want pop and get rid of what you find distracting
anyway good luck and seek out some fun walls
