Putting the amazing color and detail aside, I feel this is a perfect representation of the feeling of craving or even desire. I'm not sure if it's what you were going for, but this image looks like it's rippling, bubbling up, growing out of control. Fantastic job!
Yes, the idea is the bright yellow spot is the object of desire. Everything else is emotion and reasoning that shift between raw want and denial. As the object is still out of reach. Thank you very much for the kind words..
