I also think they're a little spoiler-y, which is why I still don't post full CGs. I think teasers are a great way to show that work is still getting done. It might be nice to do a process image for the art instead.
Unfortunately, Youtube is a stickler with r18+ content so we'd most likely be streaming on picarto for most things and possibly twitch for sfw content. I wish more platforms were open to streaming mature art!
