Here is my last personnal exercice to improve modeling from a 2D concept. This was a very enriching one and I hope you'll find it cool !
Low poly modeling in Maya, High poly and cloth in Marvelous/Zbrush/Maya SubD, Baking in marmoset toolbag and texturing in Substance Painter. The ground is made from 4 mixer layers (just for a better presentation :) )
The original concept is from Darren Bartley: https://www.artstation.com/artwork/4akdY
