i feel like if there was more of a sense of pressure building up and things being about to burst it would sell the impact of the explosion more
however when I see that in modern anime its usually feels unnatural and that its treating a solid as if its a as if its a fluid; its like a there is only one place of impact and everything travels out from that one point but really there are a whole punch of points of impact as pressure is just a bunch a lot of tiny things against a container
what I'm trying to get at is that there should be some sort or resistance to the motion
things shouldn't be moving linearly and they definitely should not have constant velocities
gravity is a thing and so is newton's 3rd law
but the lighting is good and the first part of the person being carried away with all the smoke, dust and fire and with the people seeming to just barely keep themselves from being washed over by the waves of fire and smoke
I especially like the little details in the hat being knocked of and the clothes being a ripped a bit and loose fabric getting blown around and pulling at the hole and making it a worse tear but the collar would definitely be blown around and flapping more and only the small extremities of hair are flying around when the hair around the head would also be moving up and down with the running and the lose end of the hair and the bangs would be blown around more
i think that a good comparison could be someone being repeatedly being hit by by waves waves when they are trying to move and resist them
the colors of the jacket and the arms of the womans clothing help with this overwhelming feeling because they are similar colors and make the transition from the flames to their bodies more natural and it doesn't feel like there is a barrier between them so the viewer feels like the flames are just on the brink of burning them
and the white of the woman's clothes and hair help distinguish her and her carrier from the flames but the arm across the stomach makes it so that the before mentioned barrier between the flames and the characters isn't there but that changes when they close in on her face because it feels like the danger isnt there anymore since the smoke is gone and you can distintly see the sky which is a very different color so it makes the flames and debris a background effect and not the main threat that it was made out to be beforehand
also during the close up the lack of movement from her neck or hair and just the general uniformity of it makes the crisis feel less urgent as really it would be more of a scramble to escape harms way and not a steady and sturdy jog with a carry that provides all the support needed

The first cut of the guy being crushed by a chair is great. 80s anime was so inventive when it came to killing people in horrific ways.
