Going along w/ppc_michael, I think it drags on. In general, I'd cut it down to maybe a 30 sec promo for each volume, include clearly labeled before & after footage for each segment, and don't worry about showing examples of everything in each tutorial. Show your most impressive tricks, then just list the rest or end it w/a "and many more" type line at the end. Also, since it's supposed to be a punchy VFX promo you might toss in some cool transitions between segments instead of just fading in/out.
A couple of specific comments. The "time travel" just looks like you sped up footage of a clock, I'm not sure what's happening in "TV burn in" segment, a single "photograph freeze" is enough to get the point across, thats like the world slowest whip pan in the "whip cut" section

, the perspective of the "window illusions" looks off (like the "reflections" are too big unless the couple is sitting right on the edge of the road) and there is an edit in the "reflection" footage a few frames after the dissolve from "no reflection" to "reflection" and the "green screen car" footage doesn't match-up. The keyed-in footage is a sun rise/set coming in thru the side window, but the actress is lit from the front and doesn't have the warm glow you'd get from a sun that low in the sky.
Also, you might want to put a few free samples on your site. There are a lot of other free and pay tutorials out there and people will probably be more willing to open up their wallet if they can get a sample of your wares.
