Any larger image is more important than a smaller one.
Images closer to the rim are about to happen, while those deeper down toward the base are going to take place, but they will take time. I'd also suggest that if you are reading for someone other than yourself, that you politely ask them what the symbol might mean to them. And always offer the most uplifting interpretations that may occur to you.
