I need a customized book cover

I had thought two young people (siblings she 19 years he 17 years). They are both Indians, she quite tall, both a little worn out after a few weeks on the run after a volcanic eruption. One idea is that the illustration shows them obliquely from behind with a camp below the mountain height they are standing on. The camp are survivors and consists of 100 people (not all shown) some varming in front of a fire. I can give you more details later. Kind regards Hans Conradson
