The Shakespearean hump was definitely goofy, but he suffered from terrible scoliosis...and his armour was made so as to allow a reasonable measure of movement in spite of the deformity..once unhorsed though, he was at a disadvantage in being essentially one sided, and at this stage in his life had lost fitness ..weakened thusly he was pretty much screwed. There have been some interesting forensic reconstructions of his face. Certainly his image in history was much coloured by the victors...hardly the nasty piece of work he’s been made out to be.
The model looks like fun painting...even if we can’t be sure this is how he looked at Bosworth. Would make for a great diorama if mixed into close combat with outher suitable figures
