please state how much you are charging for your recolours, also it might help to format the post a little bit differently so it's more apparent that you are the artist, there is no previous owner and you are only accepting tc. People usually do it like this:
size: 512x512
recolors: yes (tc amount)
artist: Iod
previous owners: Iod
only accepting tc
if you want to keep yours how it is that's cool, some people may be confused though. Make sure you add that recolour amount though.
