On a presentation note:
1. Use a tripod for your camera. 2. please fix your lights! You probably aren't hung over, but the lighting suggests baggy eyes. Lighting is easy. Use window light. Heck, you are even shooting with with a front-facing camera on your phone, so it should be easy to pick some lighting that works nicely :-)
Both of these things are cheap or free, and will drastically improve your presentation, IMO.
Cheers!
