Your old thread is
here. I can merge them if you want, but since you're asking to help price a different style I don't think it's an issue.
That aside, I think your chibis are really cute. ^^ They usually sell well here, but since they're black and white you probably won't get a whole lot of gold per chibi. My best guess would be somewhere between 200-500g depending on complexity? I personally would pay on the higher end of that estimate. :3
