I suggest to put the 3 dots menu on the right, after the reply, as final "catch all"
Maybe, i think having in the middle makes it easier to hit the more common actions, reply / like
I think the importance should follow a left to right direction. If you think the reply is the most important (I do, because promote content creation) after putting it on the left I would expand the icon with a label too. Adding some left/right padding to all icons will improve usability and UX.
