What are the most common mistakes to avoid when making fennel and onion vegetable soup?

What texture and appearance should I look for when the fennel and onion vegetable soup is done?
The vegetables should be fork‑tender but still hold their shape, and the broth should be clear to lightly golden with a fragrant aroma. The soup should look glossy from the olive oil and have a speck of green parsley on top.
