A Super Mario Bros. scene, this isn't a full stage but you can make a lot of things with it. Tell me what do you think about it in comments :D !
The trick was : Adding a plane , subdivide it . And each face will be a pixel , then after choosing the faces press Ctrl+I and then delet the faces , then extrude and add the materials , and a bigger extrude on some face will give a better 3D view . Like the bricks.
Simple, but a good idea. Looks great.
Thanks @Temunjin , i'm glad you liked it.
