I've just found your channel, and I love your reading - you're a natural at this! Rubber ducks give me the fear, however. Something about the dead, staring eyes...
Well, I'm not a huge channel; I'm just some monotone British guy. However, most important for me is do what you love - the passion will always shine through. I love books and gaming, so that's a focus for me. Also, try some new ideas. I love ASMR but, Jesus wept, it seems to be a lot of make up and spa videos these days. I think a new voice would be very well received. Also, it depends on what you're after. Personally, I prefer to be a small channel with subs that I can interact with.
