My favourite is the artillery gun, Its well modelled and with just the right details.
The whole thing in fact looks like a well made plastic model kit from the thumbs.
Well built there are slathers of detail for me to take away from this one.
I saw this yesterday on brickshelf! very impressive!! I love the twin cannon version, the fact that the underside is superbly detailed, the steerable mechanism... There aren't many people anymore who put as much work into their MOCs these days... congratulations, its fantastic! :)
