I've been trying to approach it the same way I do poetry writing. Which means the goal is to efficiently evoke feelings using highly specific and unexpected language. So it's not just about being short and descriptive, it's about making that short description do a lot of work. You want to leave space for people to fill in the edges themselves, but you also want to give them interesting edges to fill in, if that makes sense.
I don't know that I'm always that good at all that, but I find it a helpful way to look at things.
Here's an example from what I've been working on for this jam:
"The Orchard: Bordered by the verdant fog, the trees compete for air and sunlight, growing ever-more decadent fruits to tempt the newly created."
I like your example above, by the way! I think the "to his shame" bit at the end especially injects some compelling emotion and motivation into it.
