Begin with creating a base for a sitting Monkey. Make two medium circles with an upwards warped square in their middle. Let the above circle have 4 quarters for perfect face segmentation.
Elaborate with ears and outline of a monkey in the above circle, which already have 4 quarters for finesse.
Now, create the base for its hands and arms.
Furthermore, add two ovals and one big stone like oval structure for the feet and the lower body.
Create outline of the monkey by connecting all the circles and add a long tail to it.
Join the ovals by adding those lines that take the step even further.
Now make those eyes as you can see in the photo and time to add lines for those fingers.
Finish it by giving final touches across the drawing and color it if you'd like!
