Just look at this awesome Sinanju Stein Amuro Custom Ground Unit by abluu! Here’s a short story from the modeler on how he come up with the concept.
“I do not like this kit at first. One time my girlfriend saw someone built this kit and she said it looks nice, and last week I did a big favor for her and that’s why she got me this kit. I told her it looks too plain, so she told me to paint it orange. I immediately think of Amuro because of his Z Gundam. I also added the purple because of how much I love his Hi-Nu.”
