In order for you to properly understand my critiques of production Boba Fett figures (and the stylistic direction I chose when creating my own custom figure) I think it might be helpful for me to establish how it is that I personally "see" the bounty hunter:
Well… to me, Fett was about average height (roughly 5 feet 11 inches tall), wiry… athletically built… very much like Bruce Lee was. This was particularly evident in the prototype Fett outfit photos that ILM shot in 1978.
Later on, during the character's first film appearance, the most notable thing to me about his look was how sleek and slender he still appeared even while wearing his armored outfit. The costume was elaborate, yet it somehow did not look cumbersome or bulky in the way it sat upon his frame.
