not a bad video i gotta say, it's edited decently and you show off the characters' abilities very well visually. however there are indeed some huge pitfalls with this video that really don't do much for me.
first and foremost is the fact that you spend too much time explaining what the characters can do instead of giving actual criticism on their design, feel and flaws. the only character that i can distinctly remember you giving criticism on was xtreme sonic, but even then it was just saying "the spin slash is the most interesting bit about him".
secondly, i think the video was paced a bit weirdly? all of the characters seemed (to my knowledge) be organised in a random order, and it was really kind of weird imo. what i would personally do is organise them in a "worst to best" format, ranking them all from least favourite to favourite. it certainly would help me not be confused with how modern sonic was put before neo, but that's not the point lol
and thirdly...man...text to speech...not that great...i get that some people do have social anxiety and don't really like using their voices in videos, but that doesn't really make text to speech a necessarily good option by default.
anyway! i liked the video it was pretty cool ok bye
