To begin, draw a teardrop/egg shape with a hard pencil. Be sure to use light lines - this will be the rose’s inner bud.
Draw the "opening" of this shape.
Inside the rose, draw little petals
Close those petals into a heart shape.
Next, connect the bud and the rose flower outline drawing to create a petal shape.
Now draw additional heart shapes in your rose sketch, making these ones less regular and more open.
Draw one more petal on this level.
To draw a bud inside the petals of the rose, first draw small petals then larger ones.
The rest of the petals should bend more and face down to make this rose look more realistic.
