The introduction is one broad improvement; the transitions are a detail Lina wants to refine. Améliorer sa technique and perfectionner sa technique can both be natural. The second often suggests a closer look at how the skill is performed. It still describes development: perfectionner is useful for work that can keep improving.

| French | English | Construction |

To state a goal, use pour: Elle raccourcit l’introduction pour améliorer la clarté. The sentence tells you both the action and the intended benefit.
