Looks good to me. I did the Canon American Eagle at 200% for a local sign shop. It has an over 4 foot wingspan. I laminated the internal body, and wing structure to poster board. I wish I had laminated the whole thing to poster board. The poster printer paper isn't quite stiff enough to build with at that size. I think it would have been more durable. Its held up pretty well to have been hanging up on fishing line for almost 2 years. The second photo link below shows the head only laminated to poster board.
