That is great looking shot and if you didn't tell anyone no one would know. I have not replaced a sky nor do I plan to. For now I'm going to stay with the being at the right place at the right time, even of it costs me money. I have no issues if someone else does it. It will be a challenge for photo contest judges.
This took me over 600 shots. We were on a trip and this storm came up. My wide went for a nap, I got a few beer, sat on the balcony and with my remote kept pressing the shutter for 6 second exposures. 2011 and I still talk about it today. For me a replacement would have been forgotten in a month.
