That's interesting. I considered doing something similar on what I'm sure is the same kit. I photographed loads of wood such as kitchen furniture and bookshelves, anything that appeared to have a fine wood grain. The idea was to print it on decal sheet and cut it into panels the same as you have.
Never got any further than the photo's, flogged the kit to a chap that lives in Germany and started building ships instead.
