Hand drawn for us -->
The first Layers are for me to know where i am going to draw and how much light space to let in the sketch
Second layer I start add more layer to the bottom right of the whisk make it darker because i set the light from top left of the page. I have also added the black color to the places of wires, caps, whisks and and handle parts
For the last I didn't do much but just added some more layers to make it darker and for the light blue i changed it to make darker with do combo of Prussian blue
Last added the Highlights and shadows on all shapes. I used the Chinagraph pencil for the Highlight and Faber -Casetail for the shadows
