Composition is important to a painting because it brings focus to a main point you are trying to get across in your painting. You want a focal point which is the composition :) hope this helps!
Appositive is defined as a noun, a noun phrase, or a noun clause which sits next to another noun to rename it or to describe it in another way. The sentence can still be completed without an appositive but adding it can present more information about the subject.

D, her.
'her' is the female possessive, and we are talking about 'her own unique way.'
Since the way is hers, you use the possessive form.
