Sort of makes Hallucinatory Terrain (4th level) and Mirage Arcana (5th level) no where near as useful if you can mimic the effect of multiple trees and objects with a 1st level spell as you suggest.
Not even. Hallucinatory terrain can do look, sound and smell. So, it is really a compareson to major image to hallucinatory terrain. MI has duration of concentration + 3 rounds. HT has a duration of 2 hours/level. MI affects 3 10' cubes + 1 cube/level. HT affects one 30' cube/level. HT is an obviously more powerful spell. However, you don't need that if you are just creating a momentary distraction.
