A couple personal opinions, knowing this isn't finalized yet...
1. May be in the minority, but I'd prefer Bison's SFV look. With the fan, they want a flowing cape. The trenchcoat could flow easily too. Maybe include black hair COH.
2. I love 1:4, but seems too big and unnecessary for such an ambitious levitating
project. I'd think a smaller 1:6 would be easier to levitate, plus the obligatory setup is already going to be large.
