this is the champion build on Gundam World Bandai Collection 2013 by shunneige in Japan.  He made the stock nu gundam ver. ka looked like a baby ..  the efforts and level of details on this kit is simply ridiculous and the overall outcome to be nature.  definitely a master built.

here's a link to the builder's blog
