The clarification of course if you're like @notknow is the fact that winterwind/notwinterwind is an artist who usually takes other peoples works, rigs them, and makes them into animation.

In fact if you notice with the first two, they clearly state the original artists name in the bottom right corner. So this isn't a mis-attribution. Which is rare cause illadin37 usually doesn't take the due diligence of sorting their albums. At all.
