The best writers work several writing techniques into a metaphor, in a phrase. They don't just use metaphor on its own - because even several compacted into one sentence is tedious for readers. They combine it with contrast, personification, onomatopoeia and the like. For instance, "the sun glowed, a pearl embedded in a blue ocean" is effective. But why not add a few extra flavors to maximize the reader's experience? You could give the objects a personality, intensify the senses - say "the sun glowered" or "the dappled ocean", likening it to a painting. The key is, when it comes to metaphor, is not to use cliches.
Metaphor, especially when combined with other tools, is challenging to master - but, like most other skills, comes with practice. You probably don't see much metaphor in non-fiction, which might be your field of interest - but try adding in some when you do, and even try mixing in other forms of imagery. It will hugely impact your work and be a choice relief for your readers.
