The emblems look great. Are you attaching the foam directly to the seat? In the 80's I was a partner in a fiberglass company. We made seats and a bunch of other parts. The race only seats were most often foam glued or are attached by velcro to the seat. The street bikes normally had a separate fiberglass seat pan which was upholstered and then attached to the seat. Airtech calls these seat bases "upholstery pans". It makes creating a street seat a lot easier. Here's a picture of an Airtech CB750 upholstery pan to give you an idea.
