3D Drawing - The Terraced Hole

Hello guys! Come back with me @littlemozart. Today I wanna show you what have I created. I'd just created 3D drawing of terraced hole. Hope you like this.

You just have to make this pattern, give some dark and light shading on each side of the hole and also give a shadow in accordance the direction of light.

Take away from this side, to get the hole that looks real 

If you like this drawing, feel free to upvote, resteem, and don't forget to follow me here to see my next art. Have a nice day!
