First of all you'll need some simple basic art materials :
1. A plain white paper (preferably of A4 size)
2. A 2B or 3B pencil.
3. A good eraser
4. Coloring pencils. Preferably of various colors that go well together and the color Black is a must. I used Faber Castell water color crayons in this one. And I highly recommend this brand or any other brand of water color pencils the colors look much more beautiful if water is added to it.
5. Water (optional)
Step 1 : Drawing the Tree
Now let's get started. Hold gently your 2B or 3B pencil and start drawing soft, pale lines in subtle slightly curved shapes to create a very simple diagram (see figure below) that will represent our main tree. Make it as soft as possible and when the lines form the desired shape, start pressing a little harder with your pencil to create more definite lines. Don't worry if some of the lines overlap the main figure as we are going to color the lines black later.
It should look like something like that:
Step 2 : Adding leaves
Now we will add some leaves to the tree. Remember that this is a surreal work, so, the leaves should be drawn in different sizes and in a rather grotesque form. To draw the leaves, you hold your pencil the same way you did for the tree and start drawing some (3 or 4) ( light and elegant curves coming out from the bark and join the lines together to form leaves of different shapes. You can also draw some single curvy lines representing vines and add simple little untextured leaves to them. Take a look at the figure below to get some ideas.
It should look like something similar to that:
Step 3 : Creating the "Grid"
Piet Mondrian liked creating irregular mosaic like grids to add a more surreal touch to his works. That's what we are going to do.
Start creating lots of random lines coming out from almost everywhere in your drawing : between the stems of the tree, in the leaves, around the leaves, lines that are linking some leaves, etc. . When you are done, your the line you have created should be in intersection between the tree, leaves and lines and they should look like the are linked together but still have their distinct forms. Also, the lines can't be isolated and they should form a closed shape when in conjunction with the other lines, the tree or leaves, whether the shape created is small or big. Take a look at the figure below which is showing how to draw the lines.
Your final drawing should look like this and it would be even better if you can draw more detailed shapes and lines; but this is going to take much more time to color later.
Step 4 : Darkening lines and Coloring
Now this is one of our most important steps as we will start coloring our work. First of all you should choose an interesting color combination of 3 or 4 colors . Here are some examples :
1. Black, Grey, White
2. Pale green, Teal and Blue
3. Red, Yellow, Orange (That's the one I chose)
4. Blue, Green, Grey
5. Gold, Silver, White
6. Purple, Violet and Dark Pink
Now before proceeding with the colors, I would highly recommend you to add a little more detail to our drawing by dividing the big shapes into smaller ones. You can also add more leaves.
Now, let's start by using our Black pencil to darken the lines we made with the normal 2B pencil. You can darken all the lines in the drawing at once but it would be much much better if you do it little by little, using the intervals to color the shapes
When you have finished blackening a specific area's lines, you could color it before proceeding to the other lines. Start by using only two colors for that area.
Continue like this and start using your other colors when you judge is O.K to start using them.
Step 5 : Continuing the Coloring
I have already explained the main points now. Now you can go your own way or you can continue looking at my tutorial till the end. The figure below shows the four different colors I used and It also shows how I darkened only the lines whose shapes I was going to paint. That's it.
Here I continued the coloring. Make sure you color the shapes which are next to each other in different colors as far as possible Close shapes should have different colors.
Here is the completely colored tree. It was colored using only two of the four colors so as it can detach itself from the dark red and purple background. Keep in mind that if you use four colors (which I highly recommend), use the two darkest of them for the background and the two lightest ones for the foreground so as to create contrast in our drawing.
We're almost done with the drawing now. Continue to make sure that the close shapes are of different colors and I would recommend you to use water to improve your drawing if you used Water Color pencils.
Here is our final image. Water was added to it so as to give it a more painted look. I hope you enjoyed my tutorial and you can email me your works at firstname.lastname@example.org if you did so. Good luck !
