Great new demo reel. It is very impressive. How long have you been editing?
The only problem I have with it is the "Get clear" "Stay clear" segment. The font and text design is pretty basic and amateurish looking. Especially over that simple background.
The rest of your reel is so much better compared to that.
I suggest taking the "get clear, stay clear" part out. You want to start your reel out with your most impressive stuff first, and I feel that the "get clear, stay clear" part is your worst stuff, and could turn someone off from the gate.
When I first saw your reel i thought your title sequence was cool and then i saw the "get clear, stay clear' and thought, this stuff is going to suck, and then I saw the next stuff and was like Wow!
You want to keep your viewer going, this is great, this is better, this is Wow!
I created the "write on" effect using a lot of animated masks...once that was done, I created the particles in Trapcode's Particular. I had the emitter follow the logo as it wrote on (animating it frame by frame), keeping it just a little ahead of the mask so that the particle trail hid the hard edge of the mask...since they were all 3D layers, I just animated a camera around the effect. Creating the animated masks was the hard part...Particular is easy and works like a dream.
