Mike's Turn Again

 I thought I'd do something darker.  I've made three version of it, one with a high pass filter and a bit muted/sepia, one with just the high pass filter, and one closer to my usual style but dark and contrasty.  I'd really appreciate opinions on which version you like, as well as how you feel about something not in my usual cheerful style.

These are severe punishments at the hands of an out of control teacher, meted out in an empty classroom lit only by the failing autumn light through the windows.  

Senior Paddle Detention is somewhat like Sir Turquine's castle in Le Mort d'Arthur, but with detention slips instead of combat landing you there:

And in the meanwhile there came three knights riding, as fast

fleeing as ever they might ride.  And there followed them three
but one knight.  And when Sir Lionel saw him, him thought he saw
never so great a knight, nor so well faring a man, neither so
well apparelled unto all rights.  So within a while this strong
knight had overtaken one of these knights, and there he smote him
to the cold earth that he lay still.  And then he rode unto the
second knight, and smote him so that man and horse fell down. 
And then straight to the third knight he rode, and smote him
behind his horse's arse a spear length.  And then he alighted
down and reined his horse on the bridle, and bound all the three
knights fast with the reins of their own bridles.  When Sir
Lionel saw him do thus, he thought to assay him, and made him
ready, and stilly and privily he took his horse, and thought not
for to awake Sir Launcelot.  And when he was mounted upon his
horse, he overtook this strong knight, and bade him turn, and the
other smote Sir Lionel so hard that horse and man he bare to the
earth, and so he alighted down and bound him fast, and threw him
overthwart his own horse, and so he served them all four, and
rode with them away to his own castle.  And when he came there he
gart unarm them, and beat them with thorns all naked, and after
put them in a deep prison where were many more knights, that made
great dolour.
