I tried mixing Greens but got some neutrals too:

Here is my project:

Close up:

And for the homework I used a different photo. I am out camping at the moment and took this photo of the scene:

And this is my painting:

With the colours i used:

Lemon yellow, ultramarine blue, permanent rose and ivory black. 

I found it hard to change how I normally work as I usually use acrylics working from dark to light, and had to change to working from light to dark! I was successful in some parts but not in others! I did a few touch ups at the end with a white paint pen. 

I really enjoyed mixing different greens and learnt a lot from the class. Even the idea that you can mix a lighter green by using different blues and yellows, rather than buly adding white..seems obvious but I hadn't thought about it much before! Thank you Bianca for the class
