Awesome update! There are however two things that bugs me:
1. You can not stack the images on top of each other because it creates a one pixel thick line between two textures.
2. The outmost border is not quite even.
I have illustrated the problem in a image: https://www.dropbox.com/s/8b0231ddlvn857f/kenneyprob.png?dl=0
Perhaps there is something wrong with the render setting? Nevertheless great work!
