Looks awesome buddy! There are some bits of glue that are apparent but for a set of armour like this you can easily design use it as like a weld type join. Obviously not a weld but whatever a black smith might of used to join metal in the Middle Ages. Anyways looks awesome
You are a really cool father, building your son the armor of the dark lord himself! And that suit looks really good too. Space marine armor next year? =P
