Resource -1-2-3 Point Perspective by artgraphica.net
To prevent yourself from being overwhelmed, I suggest only studying one and two point perspective (however, if you're not confident yet, ignore perspective notes until later). Three point is generally un-used in drawings until you start getting into working with dynamics. In the future, you will be able to deal with zero point perspective where distance is implied through size and such, but for now, let's stick with being able to see shapes as well using perspective as simply as possible.
I chose the term carving 'cause you're basically cutting out the shape you want out of a square. To better explain the method, you use the square as your 'canvas' as to the surface you wish to draw a shape on. Then, through observation, pinpoint the points where the the shape you want is in relation to the square. The circle touches the middle of the four sides, and for each quarter of the square, it takes up about 2/3 of the square as part of the inside of the circle.
As well, using a grid will allow you to work on small parts of an object at a time, the 'carving' method can simply use four squares (put a line down the middle of both sides) but you can cut it up into smaller squares for more complex-shapes and for more precision.
The second guide image I made that'll be explained in Art Journal Part 2 - Once I get all the guides up, should be around the time I get the actual journal part up to supplement these with context and exercises.
This is quite basic, but it's for the people who don't know about them yet after all.
There's 15 Element/Principals of art, so about 15 of these sheets will be made.
Element of Art : Line
- Shape - Form - Color - Texture - Space - Value
Principles of Art : Movement - Unity - Harmony - Variety - Balance - Contrast - Proportion - Pattern & Rhythm
