Doh! Totally forgot the credit where credit is due part! Lemme go edit my first post I'll write up more on it! 
Couldn't get these shots in the last post for some reason, so I might divide these 9 images or so into 3 posts or 2.

Shot of the leg with the chest. Just a quick dry fit. Quick note, the fin on the shin and knee guard are not glued down, only dry fit, so you can see some gaps there in later pictures.

Joints in action. Not too bad of articulation, I replaced the paper joints with some other stuff. They're pretty tight and definitely do not flop.

Shot of the backpack detail I did. Lots of layering and I had to design those little boosters since they didn't come with the kit.
