hi izabel. omel here, "pinoy" as well, i made a bumblebee costume as well but mine belongs in the junkyard, hehe, cyback had a chance to see it during the PS3 launch in glorietta, thats where i first saw the WM costume , i was blown away,( my first attempt at cosplay, made the costume only as a favour for one of my "inaanak", wanted bumblebee to appear at his 7th bday party, by chance i came across the invitation for the ps3 launch while researching the net for the likeness of bumblebee and decided to have a go at it, it was fun!) made it out of common household items, ( cardboard boxes, plastic water bottles, discarded toy parts,tons of duct tape , canned spray paint and hotglue) ( posted a pic in cosplay.ph btw), he told me that the material of choice ( for cosplayers) here in the Phillipines is foam assisted rubber, will probably redo mine with proper materials, i stand at 6 ft, and when wearing the costume i gain about a foot more. when i finally wore it at my "ina-anak's" bday party the kids were all amazed thats why i'm really considering making one that can be worn more than a few times. hehe, the costumes you guys make are really awesome, hope to make mine even just a bit as good as yours, kudos to you, regards to cyback. mabuhay
