Thanks for the suggestion on the heat sinks. While I was happy with them the way they were, I've tapered them at the top and added some slant to the front and rear ends. I like them now too, so it's cool by me.
Textures are nearing completion. About 90% finished.
There are a few large flat face sections to do, mainly on the underside, but basically what I want to do now is add in some details like more pennants, panels, and doohickeys. However, most everything is mapped out except for a few of the ships narrow edges.
