I watched a video about "Demo reel dos and don'ts", and I'm reminded that when we send our portfolio out to animation studio or game studio, make sure that the content of our reel also suits with the type or character of that studio. So, the idea of sending the same reel to 5 different kind of studios won't be a good idea.
Second thing that I learnt is, it will be great if we put artistic touch to the content of our reel.
I just finished watched the 1st part of the video today. The link is here :http://www.animationmentor.com/webinar/replay/20080709carlos/carlos1.html
