Minor Project: Initial Sponge Test

I decided I wanted to begin working on a sponge texture. So far, I did not create this using Substance Designer, but with some images so I could create diffuse, specular, height, and normal maps with Crazybump. It's nowhere near what I want to get it to, but it's a start...I may see if I can import these images to Substance Designer in hopes that I can improve it there. I also tested out animating the displacement height for this texture as well to see what it would look like.
