Turtlecat's new belly :3

So here's a new belly design :) I really like this, compared to the last one which was too simple :P Now, the top shell design I don't like as much : It feels like it's even more complicated from the last one I had. So for now, stick with the older one. What do you think? Do you have any idea's to the top shell? Critiques/suggestions help! :D
