please critique my portfolio?

Hi
You have some nice videos. Well shot and composed.

I see is a lot of redundant clips of the same thing. The media tower with different effects for one. I'm not sure if that is a selling point. But could be, who knows.

Also the editorial clips. While they will sell, the market for them is much lower since they would only be used for a news broadcast or something like that. Or at least should be. But again, I'm sure people buy things and put in their project without worrying about the license.

Keep up shooting and submitting. It's the only way to keep in the food chain.

Good luck,
Jake
