These three paintings were created over a 2 year period. If we keep in mind the metaphorical meaning of this work it makes sense when trying to understand what the meaning behind it is.
After the first painting Marina noticed that image was painted off center that led her to realization that she the need more focus on her life.
The second image was centered, but the composition is identical to first.
Only a year later she gained perspective, as if she mentally broke away from the circles that were reflecting her mental patterns. Notice the completely new color scheme, that is always an indication of a change in a state of mind, a mind free from old patterns
