Progress - Draw this again

I made a draw-this-again-meme with my three drawings of king Jakob. 
I just did so see if I've have improved my skills, and If I have to say it myself, I have. 
The first one was drawed in 2009, the second in 2011 and the third one in 2015. 
That will say that it's 2 years between the first and the second and four years between the second and the third. 
Do you agree that I've improved my drawingskills?
