I actually started this paining probably close to a month ago. Haven't touched it a while until today.
Before start defining the shape of the main subject, obviously the gull, I wanted to determine the entire atmosphere, overcast ocean scene. The background is just thin underpainting but actually capturing the gloomy day quite well.
It was more than three years ago when I took this shot on my way driving back from Monterey, CA. I don't remember the exact place but I called the gull as "NorCal Seagull" that I remember, so not on Oregon coast.
