Realistic Rick Sanchez Speedsculpt (Zbrush)

This is a personal project I made. The goal was create a realistic version of Rick Sanchez from Rick and Morty. I use Zbrush for sculpting, details and textures. 3ds Max with V-ray for rendering, hair and fur (from 3ds Max). I am happy with the result but I think it can be improved. I hope you like it. Thanks!
