Here's a illustration of a bounty-hunter-style character.

Made in Zbrush, Rendered in Keyshot, Post in Photoshop.

I took an on-demand 3D concept art course by Ian Joyner through Gnomon Workshop and absolutely loved it! I felt like I learned a lot and really pushed myself while going through the course. I highly recommend it.
