In the process of attempting to restore, have you modified the trashed disk? Reformatted or remade filesystems?

If not, there's a decent chance the files are still recoverable, and it sounds like Holger has some expertise in it (not to actually volunteer him, but ...)

Basically you should take a whole-disk image backup of the trashed thing, save it onto a big USB stick or whatever, and see if someone can mine it for you.

Yes, that's right.

And that's a very important point in data recovery: As soon as you notice problems or failures with devices with important files you don't have a backup for, immediately stop any write access to that device! That's especially important if that device contains your operating system, as today's operating systems are writing a continuous stream of log files and other stuff to your system partition, which may make things worse (because the drive failure may already have damaged the file system in a way that causes data writes to the wrong areas of the drive, overwriting more data etc.).

So, immediately shut down your system and reboot from a "known good" system (like a Linux live system from CD-ROM or USB stick). Do not mount the defective disk, and limit access to the absolutely necessary. Then, use "ddrescue" to transfer as much data blocks from the defective drive to a known good drive with the same or higher capacity.

Correct. The main problem here is that the naive approach of cloning the defective drive will fail in most cases with the image cloning software failing on data blocks it cannot read anymore, retrying and retrying again to read it, so it may not only take ages to clone that drive (or fail after too many unsuccessful read attempts), but may even damage the drive even more.

That's where "ddrescue" gets into the game: It has a clever "binary search" approach to rescue as much data as possible, in the shortest possible time, by stopping as soon as a data block is not immediately readable, continuing at a different block of the drive (by dividing the remaining parts of the drive not yet read). That way, you have about 99% of your data rescued after very short time (if the drive has only a few unreadable blocks), then you can wait as long as you like to let the program try to rescure as much of the remaining data as possible. When stopped (like, after an hour or even one or two days), make a copy of the unmodified, rescued data, mount it and try to repair the file system with your system's file system utilities.

This does not work if the whole drive is broken, of course (for example, in case of a broken disk controller). In such cases, you can try to let a professional data recovery company rescue your files. At least here in Germany, there are companies that offer automated data recovery plans for failed hard disks that start about 100 €, so this is much more affordable than in the past, where you could say good bye to at least a few thousand dollars for that.

I hope that not everything is lost, and that there is a chance to recover at least some of your lost data! Good luck!

Nah...

Welp, I tried... pretty much all of the ways you suggested, and... nope... In my situation, data is 100% gone and can't be restored. All of the ways only gave rather nothing or the same result as the one I tried to restore before, which is most of the files, but completely mixed up into some kind of corrupted mess which can't be recognized by anything except by the recycle bin.

And I think, I've already accepted that, I'm thinking of maybe restoring these manually some time later, but in a little bit more... fresh state, since by the time I kinda learned to animate and just kind of draw in general a bit more, perhaps I can redo these, but better(?)

Not for now, anyways. For now I'll be mostly busy, and even during free time doing something... different, since R'n'D is not the only game I did some interesting content, Holger knows, I'd shown him before, like, years ago.
Nothing in here...*
