So far I have just added some procedural textures and also a bump map I made in Photoshop just making a bunch of dots, adding motion blur, and applying it to the shell.
So here it is so far, it's 1:30am, and I just got finished formatting my PC, so I'm sleepy.
I'll work on the textures tomorrow and post some more updates.
I'm also guessing rigging this little bug won't be too hard, you think?
