A technical exercise to take a preexisting video game character and create orthographic concept art for it based on the in-game art, trying to get as close to the in-game look as possible. I've always enjoyed the character of Tali'Zorah from Mass Effect, and felt her layered, pattern-heavy costume from ME2 and 3 would make an excellent challenge.
This level of detail and precision in the line art is way, way more exacting than typical for a concept art in professional work, but for this exercise, the challenge was too good to pass up.
