I like the Twi'leks, but the clones just seem a bit too realistic to me. They're certainly sharp, and obviously well done, but they lack that bit of LEGO feel with that much detail and no gloss...
The curious effect of the UCS Falcon is that after building it, you feel proud and impressed, and yet do not want to touch LEGO for a couple weeks afterwords, for fear that it could become as massive as what you just did...
