The Gnomon Workshop offered a tutorial last year which features Vitaly's Softimage workflow in a large part even though Gnomon takes great care to not mention Softimage in the description
Software and techniques explored by Vitaly include block-out sculpting in ZBrush, SubD modeling, retopo, CAD modeling in Moi3D, utilizing 3D KitBash libraries, Octane Render and Finalizing the image in Lightroom and Photoshop.
