The skyscraper-sized propellers are probably the wackiest.
Still, inventive and inspiring! I think I see some building products, well and truly fitted out for aerial carnage.
The aged sepia prints are appreciated; are you using Photoshop/CS/whatever to create the effects? I'm no hack at it, but it is amusing to consider what you might do to further the illusion, whether to try covering the flight stands, blurring/smoothing the shadows, etc.
Without color, the cotton 'explosion' on the one 'nef appears to have a base of flame and smoke. Now THAT'S enhanced by the monotone.
Your group has impressed me before; looking forward to further delights.
Salud!
Doug
Edit: Skrapwelder: We've both got the same eye on this one. ;->= I've noticed on TMP more than one poster uses them for futuristic spaceship fleets. This is the first occurrence of VSF 'nefs I've seen, and darned impressive!
