New Artwork - Lighthouse series

Last fall I tried to order some mats online for my 8x10 prints, but I ordered the wrong size by mistake, so now I have a pack of 25 8x10 mats with a 5x7 opening.
So, recently I've decided to paint some 5x7 paintings to fit in these mats. I thought doing some series would be a good exercise. My first series will be four Outer Banks lighthouses. I painted the first of these this weekend, here's how it came out. It is Ocracoke Island Lighthouse.
