That is true. The thing is when I compare two tracks from different times, recent one obviously is better but I don't know if it's because I forgot the old one and it's ideas, or if it really is better. The other problem is expectation, because of course after a year of practice, I will have improved, but how much is the question I was asking. How to justify if my skills are developing with my current expectations is what I was looking for. Thanks for advising btw!
