This is a past work. I'm posting it for record-keeping purposes. Created in December 2018.
I used a Mobile Worker as a base, swapped in a GM head, and added Ball weapons.
I didn't have a proper painting environment, and I didn't have any orange Gundam markers, so I just painted it with Real Touch Marker orange and left it as is.
Panel lining was done with a panel lining pen, and only the missile warheads were partially painted.
Thank you for viewing.
