In this video I'm showing the difference between colouring a leaf with only one layer or sometimes two layers of colour and adding many colours on top of each other.
I first sketched three leaves with a Staedtler Pigment Liner and then added colour to them.
I will colour the third leaf on the page once I purchaged Faber Castell Polychromos pencils. You will then see the difference between my Bruynzeel Design Pencils and Polychromos.
