Twilight Visitors - stages 2 & 3

Stage 2

I used the same paint mix from stage 1 to put in the tonal underpainting using mostly a rag for stage 2.
Stage 3 is the first colour pass on the sky. I chose a red/orange - blue/green complementary and used mixes of Phthalocyanine Blue, Permanent Orange, Zinc White and Lemon Yellow. I am going to let some of the warm underpainting show through the sky near the horizon and am vaguely considering making the foreground scrub land not sea...and I might need to change the title as it is really dusk not twilight.
