I previously already posted my initial Elite Ranger Armor Concept; since I felt I had learnt enough about design and I01's Covenant Art Style, I recently decided to rework my Concept from the ground up, with increased focus on functionality and readability, as well as flow and presentation. I ended up working off Halo 2's original design the most, as I deem it the most distinguishable and fitting design in the series; still, I was also influenced by its successors. I also took it as a learning experience, cleaning up my design and presentation workflow.
Base Elite undersuit concept by Qiu Fang (https://www.artstation.com/qfang).
Started with pen and paper, most work done in Procreate, finishing touches in Photoshop.
