Well, apart from the yellow I like it very much (prefer the sand coloured Lyrans myself) although different county fleets often paint their ships different colours than the standard sand - several are grey, some have camo-schemes and the Night Star county even have black ships so I wouldn't worry about it, this could be a variation for this new county you've made. I like the extrapolation from the SFC DN but I would have dropped the bar that runs across the front, it just doesn't fit with the Lyran shape (they look like Lyres actually so it shows where the SFB artists got the name from)
