I didn't bother coloring the edges of the model nor did I bother making joining strips.
Another thing I didn't remove are the Pepakura folding lines. There are plenty of areas in the model that have no fold reference points that I had to include the folding lines. I sure wish Tamasoft would eventually enhance Pepakura to allow the drawing of just the end points of those folding lines.
I have absolutely no idea what scale this model is. :) And yes, it's not the same scale as the EDF destroyer.
You'll find the schematics for this ship at http://www.shipschematics.net/. Excellent site! Anyway, if you check out the diagrams of this ship from that site, you'll notice that I also took some shortcuts to simplify the shape of the hull and make assembly easier.
