There was a thread once here with multiple 1080p drawings like this made by the same chinese girl. It was a few years back I think. Sadly I lost all of them during one of my windows resets.

Pic related is the only thing i could recover. (Sorry, I know it's low res)

I haven't been able to find any of them for some time now and now I'm hoping that you may still have those saved or know where to find them.
