Nice demo reel. I'd recommend adding some kind of contact info to the opening & closing (website, email, etc). Though I realize this demo reel may be targeted to a specific potential client, never underestimate how easy it is for someone to lose your contact info -- especially someone that loves the reel and wants to hire you.

A client asked for a motion graphics reel. This is what I put together. It's all Ae with third party plugs.
