Reflexion

First of all I want to apologize for the poor quality photo, I'm a noob when it comes to photograph drawings. Maybe someone will be so kind and give some tips.

Now let's talk about this drawing. First of all it's drawn on an A2, so it's quite big. Secondly I didn't draw like this for more than a year so my skills are a bit rusty.

Feel free to comment it I really need some advices.

Model is a brazilian model/actress Thaila Ayala. Photo reference [link]
