First, WELCOME!
Second, I don't think the 2 sabres is working. Did the explosion hit the Saber or just singe it? If it missed or just singed it, I suggest one image of the saber, with a long, maybe curved motion blur with the explosion in the middle. Translucent multiples in photos don't work as well as they do in comics.
3rd (hey, I have a lot to say!
) I'd put some zig-zag tracks in the snow in the first shot, to show some motion and excitement that they've been dodging the explosions along the way.
This is fantastic, this is JUST the kind of thing I was hoping would be discussed here.
