Painting Birch Trees

I was so glad with the results of this painting.

I used painter's tape for the closest trees and borders of my paper, and Molotow art masking fluid for the far thinner trees in the background. The surface I use to tape my paper on is glass. 

To paint the background trees I used a #2 brush and the surface is very thin. The front trees are painted with Quinacridone Gols and Paynes Gray.

List of colors I used: Quinacridone Gols, Paynes Gray, Crimson Lake, Permanent Yellow Deep and Vandyke Brown.
