ok your trying to add three D without knowing what perspective is. It just doesnt work you need perspective or the three D will be wrong 100% of the time. So this is what you should do. Go to your school, hopefully your in highschool if your in middle still ask, go to the art teacher in your school and ask if they can just give you a quick over view of perspective. Trust me this is needed for kinds of art. If you like art next year when you have to pick your classes take art, if you have a good teacher and your intrested, its a awesome class.
