Wow, I've never seen these pages before. Thanks for sharing, and I hope people understand to click inside the post.
These really are an amazing mash-up of styles. To me they look kind of like elements and lifeforms existing inside a larger lifeform, sort of like in Kerascoet's masterful Satania. I sure wouldn't mind seeing a whole story like this.
I thought that was a big part of how Spiner made Data just about the most interesting character in the series-- the understated little flourishes, tics, and burblings of emotion showing through.
To me a very clever variation on Nimoy's amazing work on Spock in the series before, but of course Brent made the character wholly his own to the point that it barely registered that he was cut from the 'Spock template.'
