Recently I finished a course of hard surface sculpting for zbrush that I've been taking in my free time for over a month now, and I wanted to show you the final result.
I learned a lot of things that really helped me understand the workflow of hard surface sculpting, different techniques and settings you can use to improve your art, reinforced the previous knowledge I had of the software; and many other things that I didn't even know you could do in zbrush. :D
The course name is "Zbrush: Hard Surface Sculpting For All Levels!" by Sean Fowler if you want to check it out.
