I have another lesson for you guys that will leave the eye wondering "is it?". The answer is yes, it is. Here is "how to draw illusion art", step by step. Drawing illusions is a very tricky process because you have to draw objects in a manner to form another object, or in this case face, without drawing it. Here you see the half image of a tree with three birds flocking to it. I'm not going to tell you what the illusion is, if you can see it, leave a comment and let me know what it is. Adios folks and have fun.
