Yeah, Exactly! ^.^

It really helps you learn perspective and shading. So i have a recommendation for you (Just a recommendation, i think it will help.)

Get yourself a pad of paper, and some pencils.

Now, You're not allowed to look at the paper when you do this. Place your pencil on the paper, look away.

Stare at your hand.

Follow the edges of your hand with your eyes, don't look away. As the edge of your hand goes up, move your pencil up, when the edge moves to the side, move your pencil to the side as the same angle if you can.

Follow all the edges you can find in your hand.

Don't worry about what it's going to look like, because that's not the point.

The idea is to practice simply seeing the angles and lines in your hands.

I'd do this once or even twice.

After you've done that, pick a really simple object like a book, Set it in one place in front of you. while you draw, don't stand up or move around. Moving around just a little bit can change the outcome. Just draw what you can see there. Try and get angles to match on your paper, and proportionate lengths (i.e. If the top of the book is 3 times as long as the sides, then it should be that way on the paper also) Don't worry so much about the outcome. Just keep doing it and finish the drawing. Later shading comes in but i wouldn't worry about it yet. (for me, shading was easy once i got contour drawings)

^.^

So yeah... Hope this helps.
