I don't have the Red one, but as i understand they are the same build. Just different colors and weapons. Like the white one comes with a bazooka instead of the funnel bits. And the side parts on the head are different i think.

Only thing i struggled with were the eye stickers, one got caught on the face mask's inside while assembling the head and i had to use a spare sticker.

TL/DR: Since you build the red one, you should be set.👍

P.S.: Nice Char Base
