It's nothing special. An outro needs to consist of a subscribe button, which I guess you have but it should also have maybe an overlay of another video of interest. Personally I have a subscribe button, video overlay, message that says "Thank you for the support" and also various social media icons, so that followers and viewers know where they can engage with me.
I think you should probably scrap the one you have all together and maybe get a picture, or wallpaper you like and type something on top of it because what you used looks very early 90s MS Word text styling.
