Empirical drawing with blue pen

I made this drawing for a contest that was sponsored by Hive account@steemjet, some time ago here on the steemit platform, I made it by hand raised only looking at the photo that was placed so that it was drawn with a blue pen. It took me almost two hours to do it so that I would stay as similar as possible. But really, I did not win, but it satisfies me, being able to make drawings without having studies of any kind
