T-Rex and Ellie from Jurassic Park Costume

My daughter is obsessed with Jurassic Park and really wanted to be a T-Rex for Halloween this year, and this is what we came up with.
The head is made from insulation foam that I glued together and then sculpted. I used spray foam for some of the extra bumps. I carved each tooth out of foam and then glued it into to the mouth using spray foam. I then painted each tooth using Shellac to make them a little stronger and to give them a slight yellowish tint. I suggest having your child try on the head before doing this, because I ended up making the teeth too big and had to shave them down and re-coat them. I painted most of the extra bumps black, and then covered the rest of the head in the same fabric that I used to make the rest of her dinosaur costume. I also carved some holes into the front of the head (on the bumps) and stuck two small flashlights inside. This was mainly so that cars would be able to see her while she was outside... and for that extra wow factor. Her suit was a zip up one piece with a detachable tail that Velcros on around her waist. Her feet were stuffed and strapped onto her shoes with elastic. For her hands I just hand painted some of her old gloves to make them look like dino claws.
My costume included khaki shorts, boots, a blue tank top, and a pink button up with blood on the shoulder. The T-Rex costume took a few weeks to make while the Ellie costume was thrown together pretty quickly.
