As I recall this was the progression of the main art's design, more or less. I didn't do a bit of it on paper, it was photoshop all the way through. That's also true of the many black and white cards, a few of which were seen in the previous entry.
These are just a few of the unused scraps that I found in the reject folder.
To prepare for this project I looked at a bunch of old sci-fi art and EC comics, just soaking in the pulpy goodness until my eyes could see the world only through Wally Wood colored glasses.
It was great fun and I hope it shows.
