Thanks for being so responsive. We like the changes to the text. I think we did a bad job of describing the brain changes. What we are looking for is to add a small bump and spinal cord to the bottom of your original brain. I also think it would be best to keep the dialogue boxes the original shape. Here is a link to a brain profile image.

We really like your original brain, just want to add the extra shape because some of our audience will more easily recognize that as a brain shape. It is fine to build off of your original shape. Thanks!!
