For a painter, any new fascinating topic is a treat. Here it's the pier at dawn, yellow lights, a warm greyish purplish sky, the sunrise adds pinks, the waves of the ocean still in a shade white, violet white.
I talked about this view before here. Though this industry is of course polluting land, water, sky in one way or another (let's not kid ourselves) it's pretty with those lights, at night, and in the morning.
ONLY paint stuff you love. That holds beauty (for you). Then the beauty can convey. To you and to others!

Often it's so ugly again soon after complete sunrise. Get up earlier!
Colors on the palette. Just a few colors, natural greys, lilacs, warm lights
Your Seascapes will get that spark of life in, when you can paint them there: standing on the beach.
Even if you don't live near a beach, you can book a holiday to a place near the ocean and start painting there.
