I've made this character for Artstation Wild West Real Time Character Challenge. It got a honorable mention.
In the archive you will find the Marmoset scene, the fbx files for the T-posed character, posed character and the rest of the environment. You will also get the Zbrush file with the high poly of the character, all the textures including the psd files and the Marmoset Viewer files for a quick study of the character.
I hope you'll enjoy studying this. Cheers!
