My timid version on cheap $1.25 8x10 canvas so did not scrub too hard. I did cover canvas in yellow. Obviously I did not follow true to the tutorial and added my own style but I am happy with outcome. I may add a few more bare branches or not. I enjoyed your class.

 This is so interesting..my cheap canvas was standing against a light and look how amazing it looks with the light showing through the yellow underpainting..
