It was similar for me! I was bored and put an UwU down on the canvas at the beginning of the event and it survived almost until the end! People kept repairing it too and put the rainbow road below without destroying it. In the end the space got repurposed for a cute pony which is for the best x3
I’m very surprised how long it lasted though! This community is so nice!

thought I’d share my version too which is more of a pixel by pixel version of the 1000x500 pixel canvas ^^

I managed to convert the colors using GIMP and updated the links in my last comment with that version ^^

I took the liberty to scale down your image to a one-to-one version and convert the colors ^^

Edit: converted the colors as well and updated the links above
old version, i.e. non color mapped scaled down image
