Finally finished this guy yesterday. Talk about a build! These Koto kits have so many small pieces compared to the Bandai kits. Though overall I really enjoyed the build. 

As for the kit itself the articulation is good. It has a pretty good range of motion and takes most poses pretty well. The shoulder assembly is a bit on the loose side as well as the back mounted boosters when opened, but it definitely doesn’t take away from the overall success of the kit.
