I started sharing my artwork on these sites as well. Those platforms seem pretty popular, and some people may prefer them for one reason or another. I also want to make my artwork easy to access.
Those uploads will follow the same familiar schedule. The upload software will handle them, so it doesn't increase my workload.
I haven't used either one of those sites before, so I'm not entirely sure how things are structured. They seem to have a bit of a social media aspect to them as well, and it could be an interesting experiment really. Time will tell!
