How much of this made it into the episode?

In his tweet, Miyazaki says these are "idea rakugaki" or "sketches and sketches of ideas" (to quote a machine translation). He gave these to episode director Itsuki Tsuchigami to get feedback and hash out how the fight might go. A lot of these ideas weren't used, and most of what did make it was tweaked to the point its hard to count it as making it into the episode

Was this cleaned up, as in drawn over, into genga and then the final? Or did they just use it as a reference?

MuddyYoshi said:
Just as reference. See my comment above. Anything that made it into the final would've been redrawn pretty much from scratch
