This idea also expresses the idea of reaching out and trying to be noticed, as we see two people reaching out to each other. but, neither of them are able to cross over the boundary that we can see. i think this idea would look really effective if the two people were created using dark tones (ie. black and white or greyscale) and the splashes were bright colours. i believe this would emphasise on a depressing emotion. i also feel this would be quite a simple, but effective idea. i would relate this idea to the Two Fridas portrait as its two seperate identities, trying to connect with each other.
