That’s an amazing illustration

I think (as you say, constraints of your kitchen table), the depth is wrong, because musketeers could not sensibly be deployed 15 to 20 ranks deep. I seem to recall that using the ‘countermarch’ tactic of each rank firing a volley and then dropping back to let the next rank march through to give fire, the optimum was around 6 ranks deep?
This would give the overall unit a frontage possibly three times as wide as you depict.
Which would then beg the question as to whether the pikemen would necessarily be distributed in smaller parties along this frontage to protect the musketeers, who would otherwise be very vulnerable to cavalry attacks.
But it’s still an impressive demonstration
