This quick lesson along with the below post, are great practice exercises even for the mature.
Perspective drawing for me is almost as complicated as the face. That is what my mind tells me anyway. So turning aside from the artsy fartsy of it all, and more towards the science of it all, I don't want my mind telling me that "I can't do this"! "YES I CAN" and "I WILL". I hope this is enough to say this morning and to encourage you and spur you on also in your drawing skills.
Remember I made mention in previous posts, I learned abstract art, not realism. So if I didn't want to put an eye ball or nose where they go on the head, I didn't have too! Sound a bit rebellious, perhaps, but now, I want to understand and know!
So, copy artists work that you love and lay a piece of tracing paper over them, and begin to draw out where the horizontal line is in the painting or drawing that you are using. Use a marker if you want so that you can see your lines later (not too thick of a marker because it will bleed through the tracing paper). Keep the copies of the original art work so that you can practice again. This is a mental exercise to learn about where the artist was standing when they began to draw this landscape. Look at what was drawn or painted in the distance. That is the background, what is in the middle of the picture-that is the middle ground, and what is closest to you is the foreground. If there is a person in the foreground, draw a line from the tip of their head to the horizon line. Do that with as many objects that are in the painting to see where they meet up with the horizontal line. Select one point on that horizontal line where all the other lines meet. This will show you where the focal point is.
I am doing an example myself and will post to show you how if you are a bit confused.
