Stream time doesn't take away from development time. Streams are used to interact with the community. Sometimes it's doodle streams, sometimes it's redraws or other changes. If, for example, a bust is getting a
redraw, it's to be more consistent with scene art and/or to increase the technical level of detail up to par with the rest since there has been a canvas size change, among other things, mid-development as Bread learned more.
We're not going down a route of infinitely having to redraw and redo things (revamped™), but we will change things occasionally to bring everything up to par, and be consistent with everything else.
