At first it is necessary to draw simply apple, its form does not matter. Let's begin with dredging in the middle and sticks, we will draw part of apple at the left.

Then on the right, we will a little darken core.

Rough lines, a little angular we draw a contour of an otkus, it can also be any size.

We erase unnecessary part of apple, and inside to a sting draw a few small curves. In total. Who wants to paint over it a pencil, there is a lesson here.

Watch still a rose in a pot, a still life, cones, a coniferous tree.
