I love the atmosphere under a dark sky. Although things do look more splendid and beautiful under bright sunlight, an overcast will make everything calm and shaded, open for new findings.
I like to imagine a world where everything is grey, and the sun never rises or sets. The weather is static and calm, and the whole land is serene.
I feel that I need to write or draw my paracosm down, so that I would not lose it after a while, which seems probable lately.
