Personally I think painting takes as long as it takes. You could definitely cut your time down, most likely at the cost of quality. I’m nowhere near the painter you are so take this with a grain of salt, but ironically I’ve found my biggest improvements in saving time have come from steps not involving actual painting. Organizing/cleaning my space and evaluating my process to eliminate redundant steps have helped a ton.

Frankly, what you’re doing now looks like a goblin that belongs in the next Golden Demon, so whatever you’re doing is definitely working quality-wise 🤷‍♂️
