I hesitate posting as I dislike it! But I did watch class. I really can't apply the concept of few colors as I have many colors by arteza but they are old and some dried up in tubes so I used various ones. So was just trying to see if I could come up with a likeness. I attach my reference. I had no idea what I should have done to paint the lower left side. Any feedback?

I am not sure if I love gouache as I dont get a good feel for it on my brush unless I wet my brush and then I guess it becomes too watery. Will keep trying.
