Full disclosure; we don’t really know the difference between sky-fi and sci-fi. One has propellors and one doesn’t maybe? Anyway, we’re sure the more professional blogs will pick these up soon so you can read a proper description there, in the meantime we’re happy just to say that they’re both rather lovely builds and that you can see more of Sylon-tw‘s ‘F-09 Trident’ (above) and Eric Teo‘s ‘Crimson Dawn’ on Flickr via the links.
