Personally I love it when the person has a mic on and also one which is easily hearable. Hearing the artist talk and engage with the chat it always super entertaining. But if mic isnt avialable then the artist just engaging in chat is also definitely a plus for me.
No lags during the stream also make it enjoyable.

Thanks for the suggestions, I recently got a new mic and (after some tinkering and 3rd party programs) people have said they really enjoy the audio quality during our test back on Wednesday. But I will make sure to keep that in mind, and of course interaction is very important. It's why I stream and not just simply record and spit out a video you know?

Lag is a bit harder to handle, trying to see how well the stream works on my end while playing the game usually takes a lot of bandwith as you can imagine but I'll see what I can do. Thanks again! ^^

On art streams I don't need the artist to talk. I often watch streams where they just have some music turned which I personally understand coz when I concentrate on drawing I can't talk at all lol. There's also been an artist that I loved watching who had Ghibli movies running in another window so we could watch the art and the movie with the artist interacting in the chat every now and then as well.

On game streams though I do like the gamer to talk ...if it's not too childish I suppose. A lot of people tend to be so damn silly and not like your usual Minecraft streams but really friggin stupid XD

I think Ghibli movies might be a bit of a problem on Twitch lol. But the rest of that I will gladly take into consideration! ^^

I mean it doesn't have to be Ghibli. It's just been nice in general. Besides on Twitch, for gaming, having movies on is not necessary at all.
