Yeah the purple bits on the Tholian ship would swirls around.

UPDATE...
More of my Klingon ship.
I've added a photon torpedo tube and some cut outs to the lower front part of the upper deck.
Second I've added stuff the sides of the upper deck. A few details behind the bridge and most importent. Two disrupters.
The last picture shows more details behind the bridge and some changes made to the neck to make look a bit more beefy.
