Rustic Barn

watercolour

Did this in class last week. It still needs work: the trees on left need dark valued leaves and trunk shadows, the driveway needs the ruts more defined, I will put some tall grass weed on the left rear of barn, plus I have to do something with the view into the open barn door - it isn't working for me.
I also think I overdid the weeds in the foreground - I should have only done a few bunches, not totally across the front.
The barn is supposed to have a metal roof - does it look like that to anyone?
