Love the fact that you added more drill motions to the game.
But:
Iam pretty sure the way "parade rest" is done is an reenactorism.
There are two version in the books and both appear to have been used.
The first is found in the part about how to relive a Sentinel. And it is not for use when at parade... but you can find photographs where it is uses anyway.
Parade rest from Hardee's revised and US infantry 1861- rifle manual of arms. (and casey for that matter)
Parade —REST.
At the command, rest, turn the piece on
the heel of the butt, the barrel to the left, the
muzzle in front of the centre of the body ;
seize it at the same time with the left hand just
above, and with the right at the upper band ;
carry the right foot six inches to the rear, the
left knee slightly bent.

PARADE— REST!
At the last word of this command, the soldier will carry the right
foot six inches in rear of the left heel, the left knee slightly bent, the body
upright upon the right leg; the musket resting against the hollow of the
right shoulder, the hands crossed in front, the backs of
them outward, and the left hand uppermost.
At the word, ATTENTION!, the soldier will
resume the correct position at ordered arms. In the
positions here indicated, the soldier will remain silent
and motionless ; and it is particularly enjoined upon
all officers to cause the commands above given, on
the part of the soldier, to be executed with great
briskness and spirit.
US and CSA army regulation are identical:
When looking up what the regulations say about parades you get this.
"PARADE-REST!" At the last word of this command, the
soldier will carry the right foot six inches in rear of the left heel, the left knee slightly bent,
the body upright upon the right leg; the musket resting against the hollow of the right
shoulder, the hands crossed in front, the backs of them outward, and the left hand uppermost.
At the word "ATTENTION!" the soldier will resume the correct position at ordered arms. In
the positions here indicated, the soldier will remain silent and motionless; and it is
particularly enjoined upon all officers to cause the commands above given, on the part of
tale soldier, to be executed with great briskness and spirit.
Officers on all duties under arms are to have their swords drawn, without waiting for any
words of command for that purpose.

States", (Richmond, War Department, 1863), para's 322-23 (Emphasis added).
In place rest
In place rest is not wrong, but there are just very few requirements so almost everything goes.
According to the U.S. Tactics:
37. The instructor, wishing to rest the men, without deranging the alignment, will first-cause
arms to be supported, or ordered, and then command: In place-REST.
38. At this command, the men will no longer be constrained to preserve silence or steadiness
of position; but they will always keep one or other heel on the alignment.
U.S. Infantry Tactics 1861 (School of the Company), pg. 96.
According to Hardee's Revised Tactics:
If the instructor wishes merely to relieve the attention of the recruit, he commands, in place-
REST; the soldier is then not required to preserve his immobility, but he always keeps one of
his feet in its place.

(1862), (School of the Soldier), para. 73.
Only rule - one foot on line... so in the perfect world you should add different ways of standing, animation of taking a drink or finding something to eat and similar... But I know this is not a priority.
