i dunno how much this would help but sometimes it's better to try and figure things out instead of depending on others? like if you feel that your ability to make AMVs are hitting a wall sometimes it's good to try and figure out what's causing that. from a critic's perspective it can also be really difficult to tell you what you can do to improve if you don't have any idea or goal you want to achieve other than just being 'better'.

i know it's probably not my place to say but it really feels like you keep looking for others to blame for your lack of direction with these...and in any creative endeavor a large part actually comes from the individual and what they want to do with it. think and approach it like your writing and figure out the reasons why you do it. while one of the rewards for doing things like that is to share with other people another part comes from your own personal goals and achievement into creating something like that. i mean if getting replies and comments were the only things that motivated me to do work i probably would've stopped a long time ago at ASMR whenever my pieces got zero feedback.

and i'm saying this because you are creative. and being creative in one area isn't limited to just that one specific area; they all have similarities that you can use. if you can write beautifully then you can create AMVs. if you can imagine a story or plot you can create a storyboard and come up with an idea in that fashion. :3
