This simple tutorial will show you how to create the basic shape of a tree.
First, draw the trunk of your tree. For this I am using RMD, but you can use absolutely any drawing media you wish!
Using thinner lines, start drawing the branches. Think of how your tree is growing when you draw.
Using thinner lines again, branch out your branches!
Again thinner lines, add smaller twigs to your branches.
...tiny twigs! If it is an autumn or winter picture (or if your tree is dead!) then your tree is finished. If not...
..add leaves to your tiny twigs! Try experimenting with different leaves, different sized trees, different colours. I hope this short tutorial has been helpful!
