The tail - well, without it, the ship looks a bit odd against the Templar and Hussar, I'll ask Xing but I don't know how much work that would involve, unless, someone else wants to take it up, but I doubt that will happen at this late stage.
The size, I thought it was ok because over all it is bigger than the Hussar, and smaller than the Templar. Pretty much what Darkpearl said. You can decide specific figures if you want, but I'd say a 90% is the top limit, but I thought it looked, odd by that point, and 88 seemed to fit better.
