Here’s my idea for the Demon cavalry; rather than having demonic knights(I may design some later, reading that does sound cool!) I thought they should use centaur-like Demons.
I had to keep the image away from Games Workshop Dragon-Ogres and Zoats, and Blizzard’s Pit Lords or Diablo 3’s Siegebreaker Assault Beasts. So I had a look at the Terror Dogs from Ghostbusters, crossed them with alligators/crocodiles and with an image in my head of a huge monstrous beast charging into the lines of shiny-armoured, spear-wielding humans I think I got there!
This was done straight onto the computer again in Painter X.
More demon designs, this time drawn directly onto the computer (I usually start with a physical sketch). These are the foot-soldiers; enthusiastic cannon fodder for the demon legions. All the troops start their existence as a larval demon (the correct rituals, feeding and sacrifices create different troop types).
My brother had the idea for the demon spawn; failed, malformed demons from who usually get eaten or very occasionally adopted as mascots. Somewhat like the wormy creatures that emerged from The Trapdoor (an old UK TV stop-motion cartoon show, have a look if you’ve not heard of it!).
This is a page of demons for a comic strip (perhaps a web-comic?). First we have a variety of warped demon Warlocks with long fingernails to weave their magic and weird cowls that remind me of rickshaws. Then we have a nasty looking Overseer who uses his whip to send the demon berserkers into a frenzy.
