Because the problem isn't so much the mistakes you made, but the time you wasted crying about them.
this illustration has a cool concept, but a terrible execution. This draw SUCKS! there are so many things I'm unhappy about and doesn't look very much as I pictured it in my mind. But I worked on it , and I wasted my time hoping it would get better at it didn't, so i'm gonna post it anyway because I really like the basic idea. And I'm angry about it.
Also the scanner killed the colors. I've used so many different shades of blue in this draw and it all looks the same. fuck (ノಠ益ಠ)ノ彡┻━┻
