That is SO cool! You've built a bridge between vintage MOTU and POP with this figure. Really well done!! The hair really looks looks as of it belongs on a MOTU figure. Repainting the eyes is a great touch. Well thought out.
Also, the helmet... NICE!! Never realized up until now that the helmet in the door is actually also a nod to the very first He-Man prototype. Your version takes that design to the next level. Fun! And wonderful sculpt too!
