PRESENTATION. Of all the media outlets in the world, GAMERS are not meant to be on camera, ther is just no PRESENCE.
Step it up with the personality, use a little bit of 3 point lighting and SMILE and LAUGH and have some good times with a fellow human or dog for the sake of the art. You are not just opening a box and talking about, you have to protect the NWR brand. Right now, the presentation feels like a little 12 year kid putting a video up on youtube. I specialize in many forms a production as well and if you ever would like some post production work, hey just ask. I can also always send you some of my favorite wine if that helps out too.
The environment background was okay, although it wouldn't hurt to create a simple set. Heck, even have some kids or yourself just paint a Nintendo backdrop while you are presenting the material.
Here are a couple things to try out if you have a helper,
While your are presenting, have someone attach a white piece of large construction paper (light blue) in the background and that will be your sky. Since your are presenting a 3d system and its games, why not then have the person hang characters from fishing line off of the ceiling in different depths to your camera (is that a phone cam?) to play with the idea of 3d. Also have them make the background into a classic mario backdrop. Then, when you are talking about the street fighter game, while you are pointing out the fact about how the camera switches angles to give you the 3d, why not have them hang a Ryu Character near you, a Sakura Character on the actual backdrop and then hang a fireball just coming out of ryu a few inches away going towards sakura.
That type of thing will really make the videos start to pop.
Just a few ideas,
Jim
