If I was to commission John to master a model... it probably wouldn't be a Macross one.
But other than that I'd love to see some of the more obscure Macross aircraft like the FL-200 Mistral.
Those Wave Fenics kits are horribly engineered. Nice parts, but lousy engineering.
Closet is full, overhead rack is full, shelves are full... actually starting to sell stuff off that I know I'll never get to.
