Hey, this was a really nice episode tbh. Not mindblowing in terms of art/animation but it didn't look like crap either and granted, the action in the episode was minimal so it's fine.
I liked how ashura has his own way of solving problems by even taking into account the fact that he couldn't destroy the tree. It really shows his caring side and well, I can definitely see why naruto is his reincanation now.
The only questionable things of the episode to me was when ashura used what looked like a rasengan (it wasn't specifically stated that it was but come on, it looked just like it). The problem in that is that I believe it was established that minato created this jutsu so how could someone use it years before him? Again, this is only a slight nitpick and I'm ok with it considering it's not stated that it's a rasengan but still, kinda odd.
Overall, a solid 4/5
