I think it is cool to see like a time laps of trees growing and changing. You know there isn't such a thing as a minor thing when it comes to bonsai. Everything must be scrutinized (spelling?) if a person plans on showing a tree. I look at all my trees and think what do I need to do to make it show worthy, even my experiments. Learn by doing and if possible show your work to others, good or bad. That way the same mistakes might be avoided by others.
