Kung Fu Panda 2
I was the Art Lead on Kung Fu Panda 2 and actually had a fantastic UI Artist. But close to the end of the project our client informed us that they wanted the UI to match a style in their style guide. Since my UI Artist was shared between projects I had to redo all the UI in a few weeks time. I did the art and she implemented it into Flash. With teamwork and a few long hours we got it done. I still prefer our original design but I am pleased that the client was happy with our final product and that I was able to match the style they laid out.
