a. One thing I learned was that everything you draw in some way always goes back to the vanishing point. I noticed that whenever you draw a new shape or object, some point of it has to connect back to the vanishing point. This makes the image more realist and accurate.
b. Connecting your shapes and drawings back to the vanishing point is essential to the accuracy of your drawing. It you don't do this then the object will not look relevant in comparison to where you drawing from. For example, when you look straight at a table , you will notice it looks fatter in the front and shorter in the back. This is something that the vanishing point will help with.
c. I would make my windows bigger so everything would be more proportional. My windows are a little small, so it makes my floor look bigger than it actually is.
d. Draw it like you see it. Don't try and draw something that is there, but you cannot see. For example, it you do not see the top of a table do not draw it. Draw the image as you see.
e. The vanishing point was the most useful tool for me. I have a tendency to draw what I know is there, but I don't actually see from the certain perspective I am looking from. I also tend to make things look different than they actually are from the angle I am drawing from. This makes my image look disproportionate. The vanishing point made sure that I only drew what I saw.
