So, I feel like I want to make a chapter about my improvement so...
Let me just say something.
Don't give up
Trust me, you will be able to improve your art if you keep practicing. Practice is the key.

So here, is a "face sketch" I did back in 2014, and let me just say,
This
Looks
Horrible
Everything is wrong about it, the eyes, face shape, hair etc
The eyes are too big, and the head is too round. I made my heads very round back then... *bleh*

Err..this...
It's just...wonky
The eyes are gigantic, the neck is fat, the body looks weird.. Bleh
I drew this approximately a year ago...? I don't know, it was somewhere in Dec 2015/Jan 2016

This I drew in July 2016, and oh mai, we're improving (barely)
Yah, nothing much bugs me in this pic exept for the clothing wrinkles and the head size (too big sjrjjahshejwjqksj)
Maybe the hair shading could be better, idk

Another picture from July
..
Bleh

I drew this in November last year, and nothing really bugs me in this picture. Exept for the way I coloured it. (and the hair)

And this is my current art

So yeah, just keep practicing and you can make your art look fabulous ☄
