If you have ideas for logo and/or background for the series you can post this here !

Id say the logo is already pretty good, background could be the NSMBW one ( https://www.speedrun.com/themes/nsmbw/background.png?v=aeefda8a ), colors are already good enough, although id say the yellow borders could be a little

@blueYOSHI I added the background to the theme and yellow borders are more dark :)
