I made a 4:3 ratio version:

Usually, I just make wallpapers in ultra high resolutions (2880x1880, or double the resolution of my own monitor); Mostly because reducing the images means simply resizing it, whereas if I wanted to  make one bigger I would practically need to start it from scratch. Also it helps that almost nobody else seems to be making super ultra big wallpapers, instead focussing on a specific resolution like 1280x1080.

Aspect ratio is something I considered a few times, (usually after trying to use one on a 4:3 monitor). the GPC wallpaper just needed a crop to 4:3 (I chose double 1024x768 resolution- 2038x1536). The result is that Glitch and the text are much larger and they won't appear smushed on a 4:3 display. Main reason/excuse I don't make separate versions of all my wallpapers is because it would sort of feel like I was trying to artificially bloat my account, if that makes sense. I've done a few resizes for myself on a few occasions, but have more or less decided that I would post them as 2880x1800 (16:10), and wait until somebody requested/mentioned other ratios before I made those, just to save myself work, since most of my wallpapers have quite a lot of elements and I'd have to move and adjust things and all that.
