If you're a Steem witness and you're instrumental in the EOSDac team, that's going to make you incredibly influential in the very near future. 
Power granted voluntarily, (and withdrawn at will) is still power.
Don't shy away from it just because evil people have wielded similar in the past. 
People want leadership, and I'd rather they found it in a voluntaryist than anywhere else.

I might also recommend lighting your green screen separately, and - if possible - at more of a distance away from your back. Part of the problem with keying it when it's so close is color spill. You're getting a little of that green on you when the light bounces off of it and onto you. If you put more of a gap between it and you, then light it separately, you'll get a cleaner key.

i tried that too and had mediocre success because i used amateurish lightning and setup. There are several things which you should take in consideration if not answered by others:
- even light distribution on the green screen with multiple lights positioned is crucial for easy filtering, one is insufficient
- separate lightning of yourself, also avoids shadowing of green screen
- a good distance to the green screen to avoid shadowing
- the latter needs also enough space overall like a separate room or area (i hadn't at the time i tried)
- the proper postproduction tool if you work on the footage (i prefere Premiere Pro, but also Final Cut Pro, Vegas schould work good) for green screen masking
- fixed exposure at the camera, because automatic can lead to different exposures with different brightness levels of the green screen -> harder filtering

-> i'm personally abandoned my intention because realized it needs a lot of efforts and money to produce high quality videos with green screen
