To me, this is one of your most delicate and thoughtful concepts. While the background is just plain white and thus appropriately minimalistic, you've put a lot of work in the main subject. The model of the brain is very detailed and I can only imagine how hard it is to get that shape down.
The idea itself is both cute and thoughtful and picks up a very old problem well know to most lovers.
I am not a big fan of the whtie background, but I guess it works here and is, as I said, appropriate.
I think this is the most direct image I've ever seen, when measuring heart and reason in one's decisions. I loved the way how a simple composition managed to get such an impact on viewers. I also liked the idea of balance in decisions, and the fact that neither heart or reason are weighing more on «the scale». The «cartoonish idea» in the concept of this work was also very well achieved, as it seems the objects may come to life at any time! Trully a great work and valuable lesson for people who may be trying too hard to carry out a message.
