When describing how someone (or something) looks, feels, sounds tastes or smells, we use adjectives.
Look, feel, sound taste and smell are all sense verbs. Here are some examples of sense verbs in action:
"You look angry."
"Her perfume smells nice."
"I feel tired."
The simple rule is: subject + sense verb + adjective.
When we want to describe a subject using a noun, we must use like:
"She looks like a cat."
"This shampoo smells like coconut."
"It feels like an oven in this room! Open a window."
