I like your Snake theme!
It's a clever design
I like the main colours you used "Purple, Blue, Green" these colours used really pops out, and the colouring is so GOOD! Plus the simple shapes used fits nicely.
I especially liked the snake hair and Eye tablet on her hoodie.
There is one thing that I would change, and that is making the snakes a little bigger. I didn't notice her snake hair for a couple of seconds.
But man! your only 14?! I'm 16 and I can't colour, and design as good as you XD
I hope my advice has been helpful to you, and keep up the GREAT work! :D
