Here is a recent illustration I did for a client presentation. It is a good example of working with a client and adjusting an illustration to meet their needs. In the initial concept meeting we discussed using an image of a brain taking a bath. After I did some pencil sketched, which I wish I could find as an example, we decided to go forward with the illustration pictured below.
I thought it was a clever illustration because it implied both brain bath and "Brain Wash." When I mentioned this to the client they rethought the message and said they really wanted to imply a bath of chemicals. To me this implied a negative impact on the brain which lead to memories of Bugs Bunny bathing in a hot cauldron unaware that he was being cooked. We decided to go with an image of a Brain bathing in a cauldron filled with a chemical broth.
Although I like the double meaning of the original illustration the final art was a much clearer communication of the clients message. I also like the art in the second version more, so it's a double win.
