Hey Everyone its been a min since I posted any work. I recently took a cgma class after to polish up my modeling skills. While I enjoyed that I realized im mos def dropping the ball on texturing. I'll include the pics for a project I was working on. 
I guess im having a hard time wrapping my head around pbr texturing. If anyone could point me to some tutorials that arnt just metal or wood id greatly appreciate it.
