Step 6: That's it for the initial sketch of Jake the dog from Cartoon Network's Adventure Time! You've drawn the basic Jake shape, so now go in and tighten your drawing. From this point on, press harder with your pencil in order to get darker lines and a more defined sketch.
Step 7: Start by drawing Jake's nose as a small oval that sits on top of where the two construction lines intersect inside his muzzle. Shade in Jake's nose.
Step 8: Use the square-like shape as a guide to draw Jake's muzzle. To draw Jake's muzzle, draw a line that starts under his nose, goes around the shape and ends up under his nose on the other side.
Step 9: Draw Jake's mouth as a couple of curved lines. Inside these lines, draw three smaller curved lines on the top side for Jake's teeth and one wider curved line on the bottom for Jake's tongue.
Step 10: Darken the shape of Jake's eyes and draw an extra curved line on the right side of each shape and shade it in.
