Al, thanks for the heads up on the Bellerophon badge. I had no idea there was a newer version. Yet, I think I'll keep Kim's version. I like it better and he did go through the trouble of drawing it. I'm not sure it'll be used, otherwise.
eltf177 & Mike, thanks for the comments guys. They are much appreciated.
James, thanks for your excellent input also. I must admit you've given me cause for concern regarding the placement of the beam turrets. I drew a quick overhead to get a better handle on it and seems there's plenty of room - at least externally. I had some doubt regarding blast effects on the 40mm mounts abreast the aft funnel so I relocated them to the boatdeck.
Meanwhile, I've done some further work on the Bellerophon drawing - replaced the Dido-style turrets with Vanguard-style turrets, some minor changes to detail and added lots of gradients and anti-alaising.
