There are many details to capture in this drawing, and the close-up view exaggerates them even further.

Use the grid method to draw the flower and the frog. Draw what you see one box at a time. Because this is a close-up, there are many lines and lots of details to capture. Go slowly and be as accurate as possible.
When you are sure of the accuracy of your drawing, carefully remove the grid lines from your paper with a kneaded eraser. This is what your accurate line drawing should look like. Do not start adding any tones until you have this drawing right.
This stage of the drawing can get confusing, so pay close attention to the example. There are many overlapping shapes and subsequent shadows. I call this the “blocking in stage.”
Fill in the darkest areas of the drawing with your pencil. Study this example closely, and lay in the shapes like a puzzle. Pay attention to the direction of the pencil lines—they help create the curve of the flower petals.
Blend out the tones so everything looks smooth. Because of the overlapping petals and surfaces, there is a lot of reflected light along the edges. There is also light along the edges of the stamens.
