I’ve only done Woody and Buzz Lightyear once and found them difficult to get right. Buzz wears a helmet, so you must do him without the helmet, or you’d see nothing inside it. So I opted for the helmet on, but faceshield open. Next time, helmet off.
Woody’s eyes were a challenge and I think I made his face a bit too wide. I may try them again, but the movies seem to have faded from popularity, so maybe not.
