I realized I forgot a small detail on my Piers drawing. I went back and drew it, then I said it's fine without it. I closed out of the picture and clicked "discard changes" and thought nothing of it... turns out I DELETED ALL MY WORK FROM TODAY. I saved the finished image, but all the new shading is gone, reduced to atoms... I'm so upset... I wanted to keep it just in case I wanted to add a background, but I guess not, my dumb butt decided to click "discard changes".
Edit:
Fixed it! It took a few days, but I learned from my shading mistakes. I think it looks so much better than the original one tho. (Also I finished this a while ago, just got too lazy to post.)
