Looks really good so far, Darran. Deck number seems about right, as you correctly inferred that the saucer rim is one deck tall. I also really like the color scheme you've got going, and I think it would suit a bridge retexture really well. I'm going to contact Mark to see if a Prometheus bridge edit is okay.
Couple things...
Use the current registry just as a placeholder, all the regs for my ship have some significance, but it will have to be in the 90,000+ range. I'll hammer out an exact number on the weekend.
Also, the ship that will be released will be the USS Athena, so if the name on the msd could reflect that, that would be perfect. I love how it's shaping up so far.
