Both the Zaku and RX-78-2 kits were released in 2015. They are my favorite molds from the 1/144 or HGUC scale. I decided to repaint them in colors and markings based on both Kunio Okawara's paintings from the 1980's and the vintage "Real Type" model kit series from the same era. The colors and markings I chose for the Zaku aren't very different from the kit's intended Origin color scheme. They are basically a slightly darker version of Okawara's painting shown at the bottom of this post. There's actually an official version of this exact kit at the MG or 1/100 scale but I really like the proportions and details on these smaller Origin kits.

Original 1980's artwork by Kunio Okawara himself, if I'm not mistaken. There's a lot of thin line markings in places as well as more numbers. The stars on the shield are also typical of this style.
