Okay, so taking a quick look at this since it fell to page 5 with no replies. Here are my thoughts:
First off, containment needs some reworking. The phrase "Due to SCP-XXXX's size and defensive behavior, containment is currently not feasible." isn't needed, and you probably mean physical containment, though you can really just start listing instructions rather than first covering all the stuff that can't be done. Miles are not a metric measurement and as such should not be used. The sentence "Were SCP-XXXX to move within 75 miles of the coast" reads kind of funny… you should probably replace "were" with "should". And so on with other logical and mechanical/writing errors that are present within the draft as a whole. Flare instead of flair, and so on.
My main issue with this is that it's kind of bland. It's just a giant mechanical whale with some vague potentially-religious mystery tacked on without there being much of a reason for it. I can only very thinly think of a reference that would tie a whale to a religious context (Jonah and the whale/big fish?) but that's not enough to carry the concept for me.
Did you happen to get the concept checked in the Ideas and Brainstorming forum before starting the draft?
