I totally agree with tomandshell, the human likeness of Koto is very poor compared to Gentle Giant's stuff.
The new Luke Bespin is very poor.
I've got a few Koto, my favourites have got to be Biker Scout, Sandtrooper's (Black & White Paltrons) and the Snowtrooper.
and i'm keeping my fingers crossed that Koto will make a Grievous in the not to distant future.
Also a massive fan of GG's stuff aswell, and looking at the quality of busts and statue's that will be released between now and the end of the year, i can see them overtaking Attakus in my opinion.
