Shouldn't that be G8?
Seriously though, very nice work Sandman, I lurve the SFM stuff, tried to do similar designs myself (old fashioned drawing style) but I'm just no good at making something look clean and functional yet also detailed and realistic like Masao's stuff.
P.S. I dunno if you've done it before but have you considered making a model of the Comet class from the SFM? It's the military version of the Daedalus with the smooth hull and big cannons, looks very sweet, my favourite SFM ship.
