We need to include the following - These are the characters you are working with.
Me in my steampunk battle gear in mid fight - firing off my 'cold gun' to freeze the invading octopus army. I would be the one taking the most amount of damage. You could also give me some kind of energy or ice shield to work with. I like the idea of me in the Guardian of the Galaxy colors.
Admiral Fluffy floating in the air with space suit and bubble helmet. He has claws attached to his gloves and like to do the bloody wet work - up close and personal. He also will need jet packs to fly around both in and out of the water.
The Ghost of Teddy Roosevelt
The four of us are surrounded by an cephalopod invasion force. We could be on land or under water.
I either imagine the Tardis flying in for a landing or for us to be half teleporting to escape the water planet breaking up around us.
I also like the idea of me holding the dead Selena while the Ghost of Teddy and the cat in the space suit are morning her loss. We are surrounded by an army of destroyed machinery and killed octopus. Any of these famous covers would certainly fit the bill.
What do you think. I would love to see some sketches if you are interested in producing a picture for me. Sell me on an idea/image and I will hire you to finish the entire commission.
