Three main things you should remember when writing a descriptive essay:

• It should have one clear central impression. It is usually presented in the thesis statement.
• You may adopt either objective or subjective tone in your description. Objective description merely describes the object, while subjective also includes the writer’s attitude and feelings towards it.
• The purpose of a descriptive essay is to present an engaging description to the readers so that they can visualize the images under description.

General Advice:

• Convey the meaning with the help of the concrete, sensory detail.
• Use more adverbs, adjectives, verbs than nouns as they help to communicate the emotions more effectively.
• The central impression is built on the details you present.
• Present the events in the chronological order.
