Ah it's nothing, the linework and that stuff can be polished with some effort so it is not really a thing but a good shading isn't easy to get.
Now that I re-read my post it sounds kind of dickish; I liked the pic, but I could easily see the errors on it, and that's what I tried to mean. I'd say that, instead of going to the trash, it could go to "failed attempt of art from some time ago". I have a folder with those, and it's pretty amusing to go there once in a while and check the shit I thought looked good and realize it was horrible. Too bad I'm not good at drawing, since I could probably laugh and then look at my new paintings and feel proud of my improvement.
