|Destruction of Worlds|
...or I would have run with them, if I hadn't spent the week with a cold.
So rather than take any new photographs for this week's challenge, I created a new image by combining some photos that I took earlier in the year.
I decided to interpret the 'post' prompt as being the word in it's prefix form, meaning 'after'. Combining it with the 'planet' prompt got me 'post-planet' and the result of my tinkering in Photoshop Elements was this--a constructed image portraying the end of a planet in a broken universe.
...huh, maybe next week I'll make something more cheerful!
