Looks like a suddent breach had opened in the sky and there's that giantic shower of energizing water flowing straight down from it. Really powerful. Different from your previous one but always top quality. Nice resolution choice also.
Very nice. I'm particularly fond of the vertically upwards stress this gives off. I see it going or perhaps sucking up rather than falling\releasing down. It would be good to see some more detail towards the bottom perhaps. Something to balance the top's detail. But that's just me. Very nice work.
