One difference I notice immediately is that Kingcrusher's videos show the chess board close to full screen, whereas yours often don't. The first video of yours I checked had the board using less than a quarter of the video space. The blitzin board window wasn't even maximized, so a bunch of other blitzin windows were also visible and distracting (chat windows, the console, etc). The next video had the board window maximized, but moves were taking more than half the screen and you had the console/analysis section taking a bunch of space too, so the board again was much too small.
Nobody wants to see anything other than the board and the moves -- no chat, no console, no other parts of blitzin (including the buttons and toolbar menus). All we care about is the board and the moves. Look at Kingcrusher's videos and see how there is nothing extraneous.
Another of your videos started with some non-chess stuff showing for the first couple of seconds. You'll lose some viewers immediately because of that, as they'll assume it's a spam or you're going to take a while to get to the chess.
I hope you find this helpful. The points I've given above are all more than enough for me to strongly prefer kingcrusher's videos, as he recognizes that visual presentation is important, and nobody cares about anything other than the 64 squares and the move list (and the 64 squares should get most of the video real estate). Moreover, every other element that is present actually interferes with my appreciation of the game. It's not just that they don't contribute anything positive.
Since I started reading the chess.com forums during break-time at work, I've realized there's actually a lot of chess related questions discussed here. IMHO, There's a ton of misconceptions but also some truth and I've tried sharing my thoughts on some of the topics around here.
However, in other things like making entertaining videos for chess viewers - I have no clue. And so, here's my favor - I started making blitz chess videos with the occasional game analysis or joke video (mainly on ICC) and commenting on them while playing it live and broadcasting it through Youtube. I've been doing it since November 2011 and have kept a consistent schedule of 1-2 videos per week for a total of just under 100 so far. I started hot and my debut video reached over 1000 views but since then it's died down and on average I get 50-100 per video.
My question is - could any interested viewers take a look at my videos and offer me some helpful advice or criticism on how to make it more appealing and perhaps ideas or ways on how to market my videos? To be perfectly honest, I only started doing these videos because I was (and still am) jealous of Kingscrusher and his success - I figure if he can do it, so can I. However, it's actually pretty hard lol
