Yes--face the fire!! Sounds like you have the stones to appreciate that "'attaboy!" and "nice vid!" types of comments really do nothing to help you get better. I suggest that if you want to make your own videos, that you buy a book or two on cinema or film-making techniques and really study how to do film-making...there are a few cinema terms like 180 degree line, mis en scene, jump cut, medium shot, establishing shot, montage, etc...that you really ought to understand. Videos are a really HUGE part of the music industry today. I like watching "some videos". I spend a reasonable amount of time on YouTube watching videos of my favorite performers, and a really GOOD video can elevate an average song....but an average video can KILL even a great song...
One of the things I think that makes so,so,so many videos bad is really fast cutting, like lots of 1- and 2- and 3-second shots...fine for effects on occasion, but a lot of younger video directors (who I call 'videots') use these types of ultra-quick shots far too much, and end up making videos that are just sickening to watch. The next time you watch a video, count how long each scene appears on-screen; and then ask yourself. "Am I left feeling visually satisfied? Or am I pissed that the director cut the shot too quickly?" I think you might see that the better videos have slightly longer, more visually-rewarding scenes that do not constantly leave the viewer left feeling jerked around.
