Based on the cover of The League of Extraordinary Gentlemen Volume I graphic novel.
But instead of the museum I moved them onto a rendition of the Nautilus. I should have made the background out of LEGO also but I got lazy.
Characters from left to right:
Allen Quatermain, Dr. Henry Jeckyl (with Edward Hyde's reflection in the porthole), Wilhelmina Murray, Captain Nemo, and Hawley Grifin.
I have no idea how the copyright goes on these existing characters but the LEAGUE of EXTRAORDINARY GENTLEMEN is the amazing work of Alan Moore and Kevin O'Neill.
