I watched the four videos you have at YT.
It's nice seeing someone not afraid to go through a broad range of effects mostly well executed.
Your editing for lip-sync is spot on great.
The "stories" with each video... eh... I'm not really good at intelligently identifying an industry standard, but they look well enough.
Looks like some Sony Vegas color correction tutes will serve these videos well.
That'll even out the yellowing tungsten shots with the full spectrum outside shots.
Couple of over exposed blow-outs and under exposed shots in there, as well.
Look forward to your next video.
