For me its all about the atmosphere of the stream. usually prefer an artist thats having convo with a mix of the stream/others in like a skype call, makes time move faster and seem less....boring?

Those who take coms in stream usually do like sketches. When you say people post refs then you either go first come first serve or pick characters you like. As far as i know there's no way to make income off livestream...but that'd be something to look through the terms of the streaming service area more then anything.

The most vital thing about streaming...you got to enjoy it. If you're down in the dumps that mood affects the people watching you.

Download a program called "Procaster". It's a piece of software that allows you to stream desktop work to a channel you run on Livestream.com. Streaming commission work means you're working on a commission and people can watch you draw as you do (either through webcam or capturing your desktop). Some folks, myself for example, will take commissions while we livestream because we can work quickly. So the person gets their artwork while they watch, and you get your money asap since they pay and then you make it. It's easy to keep track of how long things take too since Livestream's Procaster tool shows you how long you've been streaming for.
Conveniently too, you can save recordings of your stream to your computer so you can upload or edit them later for playback.

Step 1: Set up a livestream account.
Step 2: Set up a channel. Be sure to mark it as "Adult" if you plan to draw porn.
Step 3: Download and install Procaster.
Step 4: Run Procaster, set up your stream. Adjust quality settings, choose audio and video input.
Step 5: Hit the big red shiny button to start streaming.
Step 6: Tell your fans that you're streaming.
Step 7: Profit!

As for what folks like to see. It varies and with your gallery you could probably get quite a crowd just from showing off your colouring sessions.

The immediacy of being able to confirm details on a commission do make stream-coms very appealing though some artists take them as a wing-it quick pace kind and of course its always good to point out that they send refs and details by note or e-mail whichever is more usual.

Worth noting too that one of the ways to keep an eye on your livestream chatbox is to pop it out into its own window and stash it on the side.

Music and chatter are all great draws, but it's mostly an audience there to see process and maybe buy stuff. :)

I use a premium join.me subscription. It's great for keeping me in a professional mindset while still working at home (something I otherwise struggle with). Also, letting clients view your streaming their project is a great idea, providing you have that level of trust!

The chat room also makes for some good dialogue, I've found.

Oh, if you're good and/or have friends, people will watch you draw whatever. Then there's the "pre-order" stream where you're doing one big commish for the client who's watching and they're giving comments on what they want, and it's entirely up to you two whether you want a bigger audience beside you two or not. And then there's the "commish sketch" stream where you're making an announcement that everybody in the stream can get a quick sketch or lineart once they've paid (via PayPal) while they're in the stream.
