I read Sisters of Mercy by Yuval Kordov not too long ago. It's about two girls who have their minds implanted in giant war machines to fight invading demons in the post-apocalypse.
Something I noticed was the prose. Most books that get published today emphasize "invisible prose" which avoids drawing attention to itself, which is fine if it suits the material, but when you do that, you miss out on a lot of nuance. See how Kordov describes the buildings of an abandoned city as "anonymous tombstones" and describes a fence as not just cut open but "scythed" open. The prose itself if evoking feelings of violence and death.
When you write a scene, don't just think about the action and dialog. Think about how the reader will interpret it. The way you phrase things, your choice of words, which words you choose to emphasize or downplay, can alter how the reader feels without changing the substance of the content, like the background music in a movie.
