If horizon line does not match viewer eye level what problem occurs?

Correct answer: The perspective of the scene will appear unnatural

Direct answer: A, the perspective of the scene will appear unnatural. In a perspective drawing, the horizon line generally represents the viewer’s eye level. It helps the artist decide how much of the tops or undersides of objects can be seen and helps organise lines that recede into the distance. First identify the assumed eye level, then check whether the horizon line and the perspective construction agree with it. If they do not, objects may seem to be viewed from conflicting heights or angles, and the scene can look distorted or unnatural. Option B is wrong because the horizon line does not automatically alter the colour scheme. Option C is wrong because texture realism depends on marks and surface description, not simply on eye-level placement. Option D is wrong because a horizon line does not create a decorative pattern. Memory cue: horizon line equals eye level in basic perspective.
