My First Kaiju MMD Project (Godzilla x Mothra)

Yep. This is how the my fan film of Monster of Monsters would be like. A MMD Production. But I need help on how to do animations. Also, I wanted to use the Godzilla PS4 Models for 6 Kaijus (I need Mechagodzilla and Hedorah). And finally, look at how cute this picture is. AWW!!!! Godzilla is in love with Mothra. It's actually going to happen in Monster of Monsters. They're going to fall in love. What do you guys think?
