As i understand, you like anime and manga. If so, then i have one suggestion for you. Try to make model pack, based on the anime "Gurren-Lagann". Make Kamina's sword, clothes, head and hairstyle. And other characters too: Simon, Yoko, Viral etc. Gunmen soldiers (those ones with horns and maces) as agressive mobs. Mega Gunzan as replacement for the Troll-boss. You can even recreate orcs into unique gunmen, such as Gurren-Lagann, Enki, Lazengann, but only their heads; armor models will be recreated to their bodyparts, so you'll get possibility to customize your gunman. And remember about their weapons. If you will take this work, i can help you with some models.
