how do I suggest a fix on an artwork

I noticed when I chose a unicorn horn and red hispter hair that the unicorn horn has some trailing artifacts.
I would have wanted to find this image and fix it but the images are not stored here (there is no link on where to find them too)

please let me know if I can help fix this

The issue does not name a file, test, or entry point; start by locating the unicorn horn and red hipster hair artwork and determining where those assets are sourced. Done means the trailing artifacts are removed and the artwork source or contribution path is identified.
