I'm still not 100% hooked on greening up the Klingon Ships. Though they had a flavor of green on the detailing, it wasn't as overt as you depict them in your modifications. I'm NOT trying to change your mind about this, I'm just letting you know what I took from TMP's color depiction of the Klingon ships.

I've always seen green klingon ships as a curse bestowed upon Star Trek ever since Star Trek III introduced the Bird of Prey (BOP). That sucker was originally designed to be a Romulan ship, which in all subsequent material Romulan ships are depicted as being VERY green. But now with all mentions of the BOP being of Romulan origin gone, everyone started putting green on everything klingon. I'm going to miss the good old gray ships. :(

Still, how the heck are you going to get the Klingons to attack the Enterprise? It's impossible!
