I don't mind making changes
tell you what, maybe you can look where I usually get my backgrounds, and if there's one you like, I can change it? I usually go on google, set the settings for "animated" and then I type things. For you, I'd do "cherry blossom pixel background" or "cherry blossom anime gif", something like that.
if you don't want to look/don't have time, I'm more than happy to upload some of my backgrounds for you, and you can see if you want me to use one. But that'd have to wait until tomorrow cause I still have orders to finish, lol.
