To be honest, this scene is not only a scene from the WOT but from my dreams as well. The Wheel has often been a catalyst for my forays into Lucid Dreaming, or Tel'aran'rhiod, as we know it... And in my dreams, the Heart of the Stone of Tear's floor is covered in blood, like in the first two here. But I'm also trying to retain accuracy to the story, which depicts the floor as worn grey stone slabs... So, the smattering of red is my compromise. I doubt I'll keep it that way in the real image, probably more of a blend between number 1 and 4 here, in terms of the floor. Thanks for all of your feedback!
