Thanks for the input everyone. I decided to go with Sheena's on the main page. Simple reason being the more bones in the picture really helped to get teh joke across much better. I also changed the colors a little by changing the blue writing to yellow to make it easier to read. Here are the links to see how they look now on their respective pages:

I think the yellow really helped to make the words pop a lot more. What do you all think?
