The acrobat was really nice, as is Jax. Jax is actually on my "to-do" list, using the same red Royal Guard body. It was nice of Hasbro to actually sculpt the body under the robes. The only thing I was hesitant about was that the body looked a little too small. How does he compare with the other regular figures?
About the figure itself, I agree with your decision to make the armor a shiny finish compared with the cloth parts being a dull finish. And I plan on doing the entire helmet with the shiny finish as well.
Overall, a very nicely done figure.
