Is there a small detail or intriguing story that you can tell with the piece? Can you make the viewer long to visit the place, to learn more about it?
What kind of color and lighting tells the story best? Google your core emotion, and look at the results.
If a viewer were to describe the scene to a friend, what would you want them to describe? How can you reenforce that?
What one-sentence story do you want to tell with the image?
What’s your core emotion? How can you push the environment to reinforce that emotion? Do you need sad trees to make the character seem sadder? Or do you need to pump up the emotional contrast, make the world cheerful so your character seems sadder by contrast?
What emotion do you want the viewer to feel? What do you need to add to reinforce that emotion, and tell the story?
What’s the time period? Is that important? Would doing some research on the time period yield better, more distinctive results? (Are you just making up a victorian-ish world based on vague intuition, or have you actually researched the victorian era?)
Where is this image located? Is there anything special or distinctive about the location? Can you make it more special/distinctive?
What’s the purpose of this image? Think about it for a minute or two. Why does this image have to exist? Why is it so important that you’ll spend a few hours out of your finite life to create it? Is it worth that? If it’s not, maybe you should be drawing something better.
What’s the core emotion, in a word?
