I described everything there already, with.. a lot of swearing while having a breakdown:

Please help, I didn't saved it before, it did autosave, and I restarted my pc to open the autosave data but it didn't helped too. I just have two layers left now the outlines and the color with the unfinished shading, did now for the screenshot a layer for a colored background to see the whole damage, and a layer for the watermark because I am paranoid someone could steal my art again
I think it looks good. Maybe you can try to work with your mistakes to make a picture with a nice style to it. The shading looks good, i can see it working to make a very great piece of art. So maybe try to continue what you were doing and finish it, and see how it turns out. Don't give up.
