I don't think so, both volleys (i think the stills are from the second one) come at the speeder at a downward angle. Although the second one is shallower.The Dark wrote:Having not seen it in motion, this may not be a plausible explanation, but could it be a bad shot that originated from the side cannon and is traveling over the snowspeeder, creating an angle where the shot appears to be above the walker, but actually originated at the head? That's what it looks to possibly be from the still.
Also, it would have to be firing up and to our left, but then this image would have to be firing up and to our right, but the blasts are parallel as they head toward the speeder. More screencaps would make it clearer.
