I'm not a modeler, but I think it's especially difficult to come up with 'new' Bretonian ships, especially fighters. While this fighter includes bits of other Bret fighters, it adds enough uniqueness to make it... Unique.
From the size comparisons, it definitely looks like a good heavy fighter concept. Looks sleek and maneuverable, bigger than the light fighter, smaller than the VHF.
Y'know, I don't get to play much anymore, but this just makes me so happy. I've been waiting for a nice Bretonian HF for so long.
