Since nobody replied to you, I'll try to answer your questions.
Before I get started, I just want to tell you that EVERYTHING I say is meant in a constructive way, and I ain't hating you whatsoever.
So first of all you should really turn the sound up, it's pretty hard to understand you.
Next, you might want to consider opting for scripted videos instead of free speaking, as a beginner a script might really help and make you feel more secure.
Also try to improve on the really obvious errors you make while speaking: ''animal agriculture consum
es'' and not consum..?
You make quite a lot of plural form- and other mistakes, which wouldn't be terrible if you were talking about sth. less serious than fast fashion or things that might improve the world, but it takes quite a lot of the serious side away from your videos.
Please do cut some mistakes (mostly speaking mistakes) out. Same thing for the aehms... and mhmms... it is pretty hard to follow you on a rather serious subject like fast fashion if you say sth wrong, then look confused into the camera and then place a cut after the mistake, instead of cutting it out in the first place.
About the thumbnail: it's okay. Maybe you should try opting for a less big and red font and put the atomic danger thing aside. it would look much better to me.
I won't argue with you about your opinions and what you say, nevertheless in your second video your first tip to ''improve'' the world is being vegan...?
I don't think vegan or people that eat vegan are bad and it certainly has its good moments but have you tried to rise a child with vegan food?
I don't know if you read about this, but it'll die!
But you don't talk about this at all just about how much it'll help animals (which is absolutely right).
But if you talk about such things you have to talk about both sides and not just about one side because it suits your argument in that point of time.
If you talk about those things, you need to be less subjective and more objective!
Nevertheless it's good to see that some people are engaged to do sth about what's happening even if it's just a little.
See ya!
