Instead of the controlled explosives at least show that vader hit a specific pylon(s) and cause the damage and after the remaining pylons will brake from the weight.
Also if you are a lightsaber cutter fetishist maybe add this.
I checked the next shots. it can be done only with 2d elements and with clever cut we avoid to show it falling down.
As you noticed, im supporting the enhance of the blue panels with some more bright color and slight glow, to add some variety and life to that set.
