Well you need the parts to be a bit bigger since they tend to grow fast. I wanted to do spartan armor from halo for my friends' daughters but sizing the stuff was way beyond me. This looks really good so far. Personally I'd go with something other than the movie IM to be different.
dude... this is amazing, your daughter look so gorgeous in the suit, can wait to see the suit finished, soon ill be dad too, and also having a daughter .....so i guess ill try to start a suit for her in near future xD
