Art-ass and Deathly Hallows Symbol

I've done my art assignment for almost a month. I know it's such a long time to draw this such thing and it supposed to be need a less time. It caused by day-off. I attend art lesson in every friday at school but it's about 2 or 3 times I got day-off on friday and this assignment couldn't be a homework, so it should be done in the school.

And look at the picture below. Obviously. It's similar, isn't it? Yeah, the Deathly Hallows Symbol is really inspiring , that's why I decided to draw it for my assignment.
