Cause i m into this i m gonna be honest, you need to work more . Try to draw perspectives of spaces and objects, ancient greek
sculptures or parts of them heads, arms, legs and their clothes . Try to have many layers between black and white and give 3d
forms from that, use pencils B5 up to HB and try to be more realistic those draws are kind of plakat ( 2dimension draws ).
If you want to make a porfolio ( a book of your work) need to work hard have many different kinds of drawings
( spaces, furnitures, figures, sculptures and objects) dont start use color is to early focus on black and white is very important .
From black and white and the tones between you gonna learn to give dimension to your drawings .
To start a pre school before is a very good idea it gonna help a lot . Remember that the key is to focus in your
drawings and work hard, is very important .
Wish you the best
