Anatomy comparison - Young boy/Teenager

I hadn't done a sort of 'tutorial' for a long time. ^^' I pretty like them, in fact. X3

This is a drawing of my OC Hayato, so as to show the evolution of the expression, the face and the 'anatomy' compared to when he was young, even if I am not specialized at all. It is only the way I proceed.
What is similar is the same 'sad' look in the two representations. ><
I hope it can help you to create, design a character.

I may do the same for girls'. But this time, I wanted to upload a boy's face. :> And I should do Hayato's description, some day. .__.

I basically wanted to try my new Fine Colour markers, since I ordered a set of 48 markers. ^^'
They quite look like promarkers, both are very convenient, and complementary.
