I feel I'm getting closer to the effect I want - these 2 paintings were done in relatively small size (9"x12"). The more successful of the two on cold-press 140LB Canson paper. The paper I used for the other one was too light and didn't give me the diffuse effect I was looking for. And the colours are more South Pacific than Killiney!
Now the challenge is to achieve the same effect in a larger format - I'll tackle that tomorrow!
