So I watched the Mario version and this side by side.
The runs were pretty much identical apart from...
...5-1 where Mario uses a walljump to climb the wall and Luigi bounces off of an enemy without a walljump. The difference is hardly noticeable.
...5-4 where you need to slow down in front of a fire pillar, due to Luigi's slower speed I assume? It seems like you could have built up speed better after letting the fire bar pass... Maybe you could have entered a corner to get more to the right side of the screen in order to avoid the fire bar?
...6-4 where you wait for the fire bar to pass to go the lower route (Mario run goes upper route). I found out by testing that you can simply jump through the fire bar with proper positioning and it may be applicable with Mario as well, see
here. In the same level you slow down needlessly when entering a corner (Mario run shoots both piranhas, your run slows down because you only shot one piranha).
...7-4, where the Mario run jumps after entering the wall in the beginning, whereas your run keeps running inside the wall (which appears to be faster for Luigi).
...8-2 where you grab the vine faster than the Mario run due to bouncing off higher of an enemy.
...9-1, where the Mario run and your run enter the pipe in the beginning differently. The way you enter the pipe can be improved as I found out by testing.
...C-4, same thing like 7-4.
In short, your run is quite good but there are some parts that can be improved on. And putting the speed-related stuff aside, I think your run is too identical with the currently published Mario run. The parts that are not identical are rare, and hardly noticeable, and Luigi's extra jumping height only pays off in one or two places, otherwise it seems more like a hindrance than an advantage to him.
