ACT vs ACEO thoughts

Here's a little fella I have created for an ATC swap. He was created a whopping 9 times! Yeah don't ask it was a bit much for me and rather a challenge as the ATC swap is rather crafty- give me paper, and paint and a little glitter - super: give me some ribbon and stuff - yikes it takes a day to do the thing :)

On the ATC front I think I will open and esty store with them and brave the highs and lows of shoppers and the post office. However, I have been wondering what to call my stuff. I figure if I draw it all on paper with my pencil then paint etc it would be and ACEO , but what happens when I use line art  created on the  computer (and I sell this line art as art stamps) then print the line art  and colour it by hand?  While it might be a one of a kind, it sort of isn't. Can it still be called ACEO or does it just become ATC, as it is not really a print either. Any thought on this would be great because it would effect the price of the thing. Another point to ponder in this is the fact that I sell the line art stamps( digital stamps), so others too can create something with the same line art.
