the colour version of this photo is pants sky wise!!!
You've had some good advice here but I'll try to distill it;
Photo = Light
Graph = Paint
You'll probably be thinking "yes I know that". But it's the fundamental that people often walk straight past. You can't organise your photography sessions around your other chores, and just pop out in the middle of the afternoon. Great photographs require great light - and more than a little planning.
As others have said, some times of the day are better than others. You have to organise your shooting around the light, unless you're creating your own great light.
Then you need to think about what it is you're trying to convey, as others have said, it's about context.
If the shot of the crane, was backlit with a dramatic sky and a little more context, is that a picture you can see in your mind, is it better than the one you've taken?
The 3 key ingredients are:
Light
Composition
Story
If you get 2 of these, you'll be creating good pictures. If you manage all 3 your pictures will be great.
Have a look around at works by great photographers and see how simple it really is. It isn't about pointing your camera at something that looks 'OK' to you and then trying to polish it later, it's about finding the light, finding the story, then creating a pleasing composition.
As that meerkat would say 'simples' - except it's not really - if it was we'd all be doing it!
