Everyone changes with the time and the surrounding environment. The person (the big sphere in the middle) has underwent a major change, but the change didn't touch his inner beliefs and principals (the peeled part reveals the inside layer of the same color). The change is unpleasant and probably painful, but the person remains the same person.The second change that we can see here is the inner change. .The inner reflection (the light blue figure in the middle) of the outside entity(turquoise figure in the lower left corner) makes a profound effect on the person. The change was growing inside, and only after a while it crawls out(the brown figure in the upper middle).
