Ah OK gotcha.
Sure always room for more stuff but I still think the initial pricing is outside of the current fair market pricing for similar items already available that are far less expensive.
Example.

Not to be discouraging but it’s not how good it looks, sorry your not selling art, but how many units you can sell in bulk.
As part of your marketing plan you might want to see what it takes to be a merchant on Daz3d’s market place as it is rather massive as compared to Epics. For that matter some of the products you are current selling on the market place could be sold over at Daz with a bit of repackaging.
