need both criticism and advice to surpass my old drawing

Hello:3 
I've not drew for like 9 months bc I was busy studying for the most important exam in my academic life,and now after i finished it I return to drawing but I feel like I've lost a lot of the progress I've made in the previous summer(which is the time when I started to take art seriously) 

this is a gesture drawings I did in that time

I really appreciate it if someone could tell me where to improve my drawing to surpass my old drawing and become better in general
