Thanks Ron
Yesterday I got a little carried away!
I started doing light brown washes on the tree to lighten it up. For the first wash I used the same brown acrylic mixed with white and water, left it to dry for an hour and then used a wash of yellow ochre over the top.
While this was drying I wanted to see what the stand would look like with, covered in the foliage and if it would work. I covered the stand in PVA glue and started to stick the foliage down. When I finished, I didn't think it looked to bad and at this point I got a little carried away! I choose the spot behind the tree, applied more PVA glue and started to stick the foliage down there (also wondering what that would look like). Unfortunately I didn't stop there! As I finished off one corner, I found myself applying more PVA glue, adding more foliage, by the time I caught up with myself, I had completed 3/4 of the ground and stuck the log to the base.
