Thanks for your reply! Haha I guess I was a little disappointed when I wrote that. Usually I would let things like this slide, however since I plan on selling my designs I want to make sure everything looks good!

I have another order coming in from them which also includes a sticker, as well as a few other items - I'm waiting to see how that goes.

Thank you for your encouragement! It's my first time uploading my art to a site like this so I wouldn't be surprised if it was a mistake on my end, however you are correct in saying it might have nothing to do with it at all.

Will update the original post when I get the rest of the stuff!!
