Transformers Jet Fighter Costume

My 7 y/o son, Darren Ong, just want transformers costume this year. I showed him The Starscream costume on YouTube last year. The whole family made the costume. It was a big challenge. It took us about 3 weeks to finish it. He helped paint some parts of the costume. He designed the color and requested wider wings. We got the wood for making the frame from Home Depot. Other materials are hinges, screws, fishing lines, Lego pieces, lights and empty big boxes (cardboard). We spent about less than $15.
He loves his costume. He was able to sit crisscrossed on the floor while wearing his costume. We took him to some Falls and Halloween costume contest. He was very surprised that he won some contests. One of the price was a new bike.
We are very happy and proud for him that he gained more self confidence.
