thank you! when it comes to drawing the things, though, the size of the document doesn't matter a whole lot. it is only marginally more difficult to make them larger, and sometimes easier since small details can simply be drawn in without needing to figure out an optimal way to communicate what it is at low resolution. Of course up close they may have blemishes that wouldn't have been a factor the old way, and there is a sort of classiness to the pure 1-to-1 pixel ratio, but overall I think this is an improvement, at least for the context I am using them in.
It is funny that you should mention the cords and cables; when i attempt to draw electronic junk for any other purpose it looks like a doom wall texture, since I spent so long looking at them ages ago that it influenced my other "art," so it may be inevitable that I return to this again and again.

inexplicably only the basic one is 512, the rest i didn't upscale yet but there is a program called waifu which helps a lot with that.
