I finally got my hands on an Amazing Barbatos Lupus, so I tried painting it in a way that makes it look like Mikazuki is riding it instead of Yuuki-senpai.
The thigh and knee armor seemed a bit thin, so I used plastic sheet metal to slightly change the proportions.
The rest of the work was just to sharpen it up and fill in the holes.
This is my first time using putty and plastic sheet metal, so please forgive any imperfections...
I added some detail using surfacer!
