on your tags, you can add more in instead of just cartoon, you can add personalized cartoon, i know they are not charactures spelled wrong, but you might add that in as a lot of people might think in that direction, and then be like wow this is even better than i was thinking.
like i make mugs, mostly, and i can use tags like "pottery coffee mug" as 1 tag. so look at adding a few more words to describe your item. look for shops that are similar and scroll to the bottom of their listing and see what their tag words are. fernan2uarez is a shop you might look at for tag words, they have sold about 100, but similar enough to see what they are adding as far as tags.
also you need to up your price :) everyone else i see similar to yours, and i like yours better than most... they are at the very least twice as much. up your price add free shipping or the option of a digital ?
good luck! keep on keeping on!
