If i can say something!
That doesn't sound too bad. Maybe you could build all three and present them altogether?
maybe it´s enough if he build a nacelleof all 3 models, then is the different clearly!
Just my own opinion:
Edward was the first, then me and then was Zosho!
Edwards model is simple, but the model is not perfectly unfolded! AND no "Phoenix" pod!!!
My one has the highest part number and is very detailed (the Nacelles are much better)! But i never added the Aztec pattern! The step-by-step instructions are worth enough!
Zosho made it a bit simpler, but at the grafic work he spent more time than me!
