Thanks, all! Axlanian really sells the line perfectly, I think.
And Dat_SW_Guy, the lightning looks amazing! Personally, I agree with Cap and Eddie though - would it be possible to add a bit of lightning hitting Finn before he’s thrown backwards as well? Also, where did you get the sound effect? It sounds a little different than the other lightning sounds in the film.
EDIT: @jarbear - cropping the Finn shot might work if it comes to that, but it also might not be necessary. As it is, I think it’s only between 8 and 10 frames before Finn starts to be yanked back - so less than half a second. Picturing it in my mind, that should be quick enough that the audience wouldn’t be able to dwell on it too much. I don’t think we need residual tendrils to be licking his body as he flies through the air or anything like that. But hey, whatever Dat_SW_Guy feels comfortable with, I guess!
And I was actually just thinking about a potential smoke effect. The thing is, immediately after being tossed, Finn crashes through a wave. Theoretically, would that put out any smouldering on his clothes? (Genuinely asking - I can’t speak from first hand experience of being struck by lightning.)
