This is a drawing question and has no single correct answer; it is assessed on the following points.
Option A - the room seen through the eye of the fish:
1. Viewpoint: draw from inside the aquarium looking out, so that the glass edge, the water and the bubbles frame the view and the room appears slightly distorted and enlarged.
2. Content: show the girl close to the glass, large in the foreground, with her face and hands towards the fish, and the furniture, window and walls of the room in the background in perspective.
3. Composition and proportion: the girl, the fish-eye frame and the room should be balanced, with a clear foreground, middle ground and background.
4. Colour or tone: cool blue-green tones for the water, warm tones for the room; show depth by overlapping and by reducing detail with distance.
Option B - a scene with fish, a girl, boat, farmers, tractor, trees and plants: include every named element, arrange them logically (water with fish and boat in one part, field with farmers and tractor in another, trees and plants framing the picture), keep the relative sizes sensible, and use colour harmony and a good horizon line.
