The drawing seemed to lack definition, so I went in with a pencil and added more details to the large foreground trees, indicated a large rock on the right side and added a pine tree.
With the fine liner I put more cattails in front of the island and also a few more of the water ripples.

Next I added some of the branches and needles onto the foreground pine trees.
I kind of like the way it looks, having a mix of the pen and ink and graphite pencil.
I will post this drawing again once I decide if I am going to leave the drawing as it is, or when I have completed the trees on the island.
