3D character created by me using as a reference sci-fi stuff that I like, such as Titanfall and images of other games and artists.

High-poly model sculpted in Zbrush and some hard-surface parts modeled in 3Ds MAX. All the PBR textures done using Substance Painter and photoshop just used to creating decals such as texts and logos.
Character Rigged in Maya (Thanks to Ehsan Kiani) with IK and FK controls and facial Rigging.

3D model rendered using Marmoset Toolbag.
