Oh ok. Sorry. I didn't know wich artist makes the original. This is a friend who sent me the photos of the original artwork on my phone. In the comments I said that I used a model.

Now, thanks your help, I know the artist.

But I drew this drawing in January 2015 and in this time, I learned to draw with models (this is "modèles" in french but I don't know the english word) and I loved the movie "Frozen".

I found this drawings really cool and I decided to draw the same with only my pencils.

I'm very sorry for that. Now I will copy the link and write this on the text.

Thank you for the information. Have a good day.
