Been working on some customized Discovery-era ships for possible use in game modding and thought I'd share them as I build them.
The first finished one is a Crossfield-class starship (sans the shroom-go-vroom). Most notable changes to the ship are the thicker pylons, raised nacelle mounting points and customized nacelles themselves.
