I've finished my MG Gelgoog Cannon! ^_^
I made a slight mistake. The arms and thighs were supposed to be black, but the molded color was red, so I painted them red.
The base colors are MS Sazabi Red, German Gray, Navy Blue, Silver, Battleship Gray, MS Metallic Gray, and Semi-Gloss Black.
Also, I changed the hands to 1/100 Zeon hands.
This kit is version 1.0, so the skirt part isn't articulated. I was able to buy the MG Gato Gelgoog in the last Premium Bandai sale, so I'm looking forward to August.
