Self-corrections

I have a travel notebook that I've carried around since 2013. I rarely go back to change earlier pages, unless its to make my own handwriting clear after a visit to a museum.

This drawing, from 2014, was always one that i liked but it bothered me for some reason. So yesterday i saw what was wrong with it, and absentmindedly corrected, improved, and finished it. I'll try to find a picture of the old drawing to see if i can make a comparison.
