Pencil drawing -New competition no 55

This is my entry drawing. I'm confident you'll like my drawing. I've put in my best effort and hard work to create it.
This is a simple drawing, but I've created a beautiful scene within it.

Firstly, I designed a circle shape in my drawing, then created an old tree. While trying to make it realistic, I added shades and used an 8B pencil. I drew some birds, and the result is very beautiful and good .
