I've started working on a highly detailed set of schematics for an updated version of the Galaxy Class, specifically the USS Venture. This will be a post Nemesis era upgrade, and center largely around upgrading the Venture's combat capabilities.
I plan on doing all five views, as well as a history of the ship from the time we first saw it in DS9, up through the upgrade. The write up will also include details about the upgrades themselves.

So click the thumbnail, and take a look at the changes I've already made. I should say now though, that the phasers are largely just place holders right now. I'm going to do something else with them, I just haven't decided what yet. Let me know what you think.
