You can repost your own art.
It's OK. Repost it. Repost that old thing from years ago.
Repost that thing from 6 months ago that didn't get enough traction.
Repost that thing from 3 months ago after you fixed a weird error on it.
Yeah, if you show someone the same image over and over in a short time, they'll start to ignore it (including multiple WIPs of one piece - always be prudent with WIPs imo). But also, the internet has a pretty short memory. Even just like a month later will refresh an image in most people's minds. You worked hard on that art, so bring it back once in a while.
