I have this habit in everything that I do where I am extremely dissatisfied with how something comes out, and I continually work on it or worse, scrap it and start from scratch. This has effectively killed my ability to write songs. I'm trying to stop, though.
I see so many mistakes, imperfections, and things that I just plain wish I'd done differently in those edits, but I've decided to leave them be and try to use them as guides for things I need to pay attention to in the future. In the edit for Kreis's sig, it drives me INSANE that I forgot to remove that stray shell that overlaps her leg, but luckily for the sig itself, it didn't cause any issue. Same thing goes with the "newnox" edit, though both of those images were made explicitly to become sigs. With the "newnox" (boy, my naming conventions sure are original and orderly), I wanted to give the feeling of the system coming apart around him. (Obviously?) I made that one when the end was announced. Like I said, I really want to stop being overly critical of my work and take it as it is instead of constantly going back and redoing things again and again.
