well I will defiantly support you if you want to start a youtube channel but one thing to consider is do you have the equipment like the camera or Phone a tripod and a good microphone with some quality editing software also ask yourself is it for a hobby or to make a profit back? other then that all you need is sufficient lighting so you don't get a tinted colour while recording if the channel is art related also if its a serious channel then i would recommend advertising it here on DeviantArt on a Journal then your watchers can find you and pass on the word
I would mostly be using my phone atleast til I got a camera. A friend offered me to use hers but Id rather. Just since its not my own thing I'm weird with those kind of things. I would mostly do it for a hobby but if were to get bigger I would love that. I know that means a new list of things to look into an doing/spending more time with it.
