I was painting some flesh on figures yesterday (not Strelets as it happens) and was marvelling at the fingers. Not so long ago a simple, ball hand was sufficient *at this scale*. Now we routinely have hands with detailed fingers. These hands may be wrapped around muskets, which are represented not as a simple 'rod', but with separate barrel and base, metal bands and strap.
Then we come to masters like these with the detail of the pockets, cartridge box, shoe buckles, belt buckles, texture of the coat... marvellous!
