Finally had the time to scan these in.
The USS Dreamstar is an Advent Class heavy cruiser designed to gracefully intimidate all who threaten the Federation. It was built some time after the Enterprise G was built.
The Spyder Class light cruiser is built for reconnaissance and science missions.
The Corvus Class is built as a "get in, get out" spy ship, built for recon and speed.
And now my personal favorite of all the designs, the Integra Class, a diplomatic/command cruiser capable of planetary landings.
