hmm, what you basically do in the video is guide people through her abilities and I expected more from a guide than that because one can find out all needed information by just reading her (detailed) ability descriptions. you did provide some info about her role and items, but considering you're mostly covering her abilities, I think you should have done more thorough job and be sure you're as accurate as possible when doing so.
I'll give few examples of what I mean.
for her stun ability, I don't remember you mentioned/demonstrated a very important thing and that is that it gives her quite a significant auto-attack speed boost. this makes for the big part of her carryish potential. so you're missing one big part of her ability, not just some minor side-effect.
you also missed saying that chaining of her stun hits closest targest and that one can abuse that fact to stun the enemy for longer by actually hitting another enemy unit (creep).
for her power throw, I think you said it cuts/destroys trees only when it's boosted by her ulti and that is just not true. it always cuts/destroys trees. ulted form just gives it global range and no damage reduction. you should be especially careful not to give false information to your audience.
what would have been nice here is if you had mentioned other ways of using her ability. saying what ability does is nice, but giving various examples of its usage is very helpful.
for instance, mention that you can also use this tree destroying ability not only to chase, but to juke and save youself. one example would be aluna getting dived near her tower, she goes deep into the trees and power throws to make a path out.
another example - aluna can make a path in trees for her teammate to get into great position for a kill attempt. for example, just think about making a path into the trees for your devourer so he can hook an enemy from totally unexpected place and keep him blocked in trees.
also, because power throw gives vision (which you mentioned iirc), in case of no wards she can easily and with impunity scout for any kongor kill attempts by ult power throwing there.
I can't recall anymore, but you also might have missed mentioning that she can easily double and triple stack neutral camps by using her power throw. especially with power throw in ulted form and she doesn't even have to be close to the camps. take a look at the minimap and you will notice some combinations of 3 camps which lie on a straight line, which is quite convenient

.
I have watched some of your other video guides and I noticed the same flaws. I don't want to sound harsh, I hope my remarks will be taken in a more positive way and hopefully nudge you to make even better guides in the future. what you do is without a doubt a very good and useful thing for the community and we thank you for it.
