Other misc:

xulm

Xulm has made these really interesting looking ship things. Awesome.

MisaQa

In my opinion, here's a master builder, MisaQa. Incredible animals and little buildings. Amazing posing too.

nermal

Nermal has got some nice little mini scale vehicles here. Check 'em out!

Faraday81

Faraday81 has some terrific space/future/sci-fi creations. You'll have to check out his Brickshelf account, by clicking on his name, and see some of the other things he's made, like some amazing microscale ships.

SPOOK

SPOOK has created this ship with some great little details. This is Spinal Fury:


He has loads of other great ships too! i think what makes his designs unique and interesting are his uses of color and shape and assymetry.






Fortunately/Unfortunately the more you dig up on this guy the more greatness is found!
I can't resist, here are some of his other creations:
Locust

Crab Tank

And these Hover Bikes

Landmarks

There are many people that build famous landmarks, and this guy is one of my of these builders. TORGUGICK, has done many, but the Taj-Mahal is so creatively done, it wins the prize in my book.
