I hand-painted the HG Gundam Barbatos Lupus, imagining it standing on the Martian landscape.
I then used a digital diorama maker to create a background that matched the image.
These are the composite image and the original image.
This piece was created in 2021, and I had planned to actually create a rocky surface for the diorama, but thanks to technological advancements in recent years... I didn't need to.
