To be honest VGM, I know absolutely F*** all about Metroid beyond the character's name and that Samus Aran is a chick... with some killer fan art.
I do, however, appreciate ingenuity and you've got it in spades with your addition of that LED and where you've placed the battery and switch; Also, that idea with the RCA Male/Female plug for the swapping of hands is also quite brilliant!
Beyond that man, I can only say that it looks to be one well approached and articulate figure; have you ever thought of turning your hand to TF customs?![]()
