since we have chosen to disect the animation, so be it:
The smoke here was done in a light grey/green through which you can see everything. The fire was also unlike TMS style. TMS is famous for its beautiful explosions and fireballs a la ROTJ or any of the TNBA/STAS episodes. The episodes, apart from both being well animated, do not share many similarities. Also, look at Dong Yang's work with Judgement Day juxtaposed against Sins of the Father. Animation varies from episode to episode, possibly retaining general techniques and even those are different in You Scratch My Back from TMS's normal conventions.
