From Sketch to Controller Design Project.

Using REFERENCE_0 as the original concept sketch, convert it into a professional industrial design presentation project for a high-end wireless game controller. While preserving the overall silhouette and control layout of the sketch, reinterpret it as a realistic matte black product, adding ergonomic sculpted grips, rounded shoulders, refined seams, tactile buttons, analog sticks, D-pad, shoulder triggers, delicate metal rings, and premium material finishes.
