Here's a collection of Guild bosses I've created for Knighthood at Midoki. They are giant bosses that a guild will take on together, usually as part of a specific event.
As we have a relatively small team of artists, we all take on a variety of tasks. I often will take an idea from inspiration, to concept, to in-game asset. We have a very speedy pipeline and the concept stage is often very brief with a focus on efficiently communicating the design.
My work also includes armour, weapons, characters and enemies, but this section is specifically for bosses.
