Three years and two days - I did say not to hold your breath! Hopefully it was worth the wait, certainly I'm pleased with the result:
One of my reasons for picking the Auriga for my next project (other than it being awesome!) was the availability of a screenshot showing it and the Delphinus side by side after the battle off Esparanza. This made scaling it to the Delphinus a cinch. Another advantage is that once I'd figured out the hull it can largely be applied to the other flagships.
The turrets and bridge were real challenges. The turrets don't look great, but they do rotate. The bridge was just the best I could make and the first thing due for a fix if a better idea occurs.
Really need to make a better stand too, but that's not exactly high priority. The only thing outstanding is a little detailing on the engines - I know what I'm doing I just need to pick up the parts. That's why they look a little gappy on the following picture recreating the shot from Esparanza.
Theoretically it'll be a lot sooner I next churn one out, given I have the hull down now. Thinking maybe the Draco next.
