I did these as a speculative submission for the comic 2000 AD - they have a bunch of sample scripts you can download on their website here, and ask that prospective artists do one of those to show what they’ve got (If you’re interested, this is my version of the script titled “Holed Up”). It’s a lot of work for no money, but it’s 2000 AD, so I’m doing it anyway.
I really enjoyed doing all the shiny metal. And the Kirby Krackle. My only regret is that there aren’t more actual human beings in it, as I would have liked to have shown off my figure drawing a bit more.
Wish me luck.
