The video are looking better and I think you're a great public speaker.
One thing I think would gain from being improved on is the whole look of the video, in particular the background and the sound.
We all know brands need to take special attention to their look and this I feel will come a lot from how the Steemit video look.
I feel like the camera is doing the job but the background could obviously be better without require much work. Even a brick wall would have been better.
Lighting is okay I think.
The sound could have been better. There's an audible noise through out the video. Sound processing to remove noise below a certain level could have been great.
It might seem like these are details but I feel like they are important ones and pretty easy to fix. Also once they're fix it easy to continuing apply those fix.
Simple suggestions whether you guys implement those or not.
