I think twitch has been good for her as an individual- she has definitely become more genuine and herself.
However it is notoriously hard to grow on, probably the hardest platform to have success on, and I highly doubt she will make it too far unless she really really dedicates herself. Obviously she may just be doing it for a fun side project, without too much ambition for huge success/followers/subs, which is totally fine. But I do wonder for her future, as she seems way more passionate about twitch than youtube so she could choose to prioritize it more, but the difficulty to grow could become an issue financially if she did. There's so many "beauty" influencers who have started twitch in the last year or so: sophie, sophdoeslife, sophie foster, roxxsaurus, steph toms, lucy flight, even anastasia kingsnorth and emily canham who have mentioned wanting to try it. Despite pretty much all of these people having an audience of around 100k+ beforehand, none have been that successful. I'm pretty sure Sophie is the only one to regularly be over 100 viewers, which is actually in the top 1% of streamers, which shows how hard it is to grow. (kinda OT but it's interesting that every influencer who has started/mentioned twitch is friends with talia mar and some have also mentioned her being an inspiration/help to them. I think some are clearly on twitch for money/clout, likely after seeing the success she's had, forgetting that she started out in a similar position to them despite her previous following and her connections, and had to stream daily for hours and make an effort to interact with the twitch community to reach where she is now.)
