Here goes the sample thumbnail I made up for you. Took roughly an hour or so, wanted to give it a shot and appreciated the videos you had up.
With this sample, you have the obvious added text based off of your title already, which I think should still work.
Also did some coloring and lighting to try to make the image pop more but not too much. Hopefully I accomplished that.
I appreciate the opportunity to take a crack at this. A suggestion for the future if I may; keep this style of scene, but move the mic out of the way for the mini-photoshoot you do. I think that will be a win-win for you in the long run.
