>>6583615not bad, i would recommend you to always use higher resolution than you need for this, this way people with high res screens can use it. 3840x2160 would be a good resolution. and pure black often makes it look a bit unfinished, so i would recommend to either use a specific color that fits a theme or colorscheme or leave it transparent (in most Operating systems you can set a default background color that will be used instead of transparent space in your wallpaper. keep it up.
do you still have the svg files for it?
