Summer Dream Vacation: Giant Underground Beach Cave #2 of Tropical Island

Concept & Entry candidate for DC #348 "Your Dream Vacation".

My illustration of a summer dream vacation: Giant underground beach cave of tropical island with sunlight shining in through a huge hole in the ceiling above. Notice the couple walking along the sandy shore in the middle, and the housing area on the left in the distance, illustrating the incredible size of this voluminous cave! A special hidden getaway to spend weeks, suitable also for larger groups of tourists with camping equipment for the shadowy and rocky areas of the beach.
