I like the loss of the blue lighting...one of my least favorite things on the JJprise. Also, you mentioned the bridge and sensor dome eventually ending up white...I like the gold with the depth you have now...personal taste. But, to me, it adds quite a bit of detail. Also, just as a thought...the 3 round windows at the fore of the primary hull on the Defiant might make an interesting detail (and change) to your un-named ship. The Lexington? :-)
I like the blue lighting I wish he'd kept it!
