This third preview of David Sidebotham's cover art for "Tides of Impossibility" shows a very different figure than the last two. Like the first, it is inhuman, and you can see some similar imagery in the design. But it is closer to human, showing a very human design, and shares minor visual queues with the human figure featured last time. This figure will also be the only one of the four whose face is visible.
