I think that I saw on discord that you haven't included text yet as you were waiting for someone to claim it.
I really like the coloring, stroke and render fx as well as a nice JC/logo. The grey spots are a little off, maybe would have used a layer mask of the render on those, but just a minor gripe. Lighting on helmet is good as well as nice render placement. Will be interesting to see what font/text you come up with and how it will compliment the current look.
