Hi mate, take it in and suck it up/// You can never please everybody and unfortunately the "heavy critics" and "trolls" will be the first to react. So don't be surprised if it stays negative for a while, just ignore that, and try even to get something positive out of that.
The videos i have checked so far are quite o.k. of course there is always room for improvement, but my personal opinion is that at least there is nothing wrong with your voice, in fact you have a pleasant one, reminds me a bit of someone that could host a radio interview
It sounds like your a modest guy, (i gather that from your happiness with that 200x, the amounts you say you deposit and the way you talked about the comments on your channel saying "fair enough")..and i found the video amusing.
Maybe if you grow into these videos more, do another 100 or so, it would add a tad of self confidence, which may reflect in your voice and of course you can always play back the videos you posted, and play around with an editor to perhaps cut scenes that might be filled with rambling and where nothing else happens on screen. There is so much possible yet, to make these videos into top entertainment
Mind you those are just friendly suggestions, in no way do i feel improvement is really necessarily, the way they are now, you know that what you are seeing is just another player like we all are, who is recording some wins. which is at least an authentic view on slotting.
Keep 'em coming.
