"Shrimp Trawler on the Creek" Use of Color and Value Contrast

The painting "Shrimp Trawler on the Creek" is an alla prima oil painting I'm working on for an upcoming show.
In it, I've used value and color contrast to portray sunlight breaking through storm clouds over a Lowcountry creek. The yellow of the afternoon sun contrasts with the dark blue of the storm clouds adding a sense of drama and visual interest to this otherwise peaceful scene.
The painting is is one of several new pieces in progress to be included in a show I'm having this fall in Charleston.

A visitor to the studio says it reminds him of one of his grandmother's nursery ditties "Shrimp Boats Is A-Coming". It's a charming old southern folk song with these lyrics:
"Shrimp boats is a-coming there's dancing tonight. Shrimp boats is a-coming there's dancing tonight. Won't you hurry, hurry, hurry home. Won't you hurry, hurry, hurry home. Shrimp boats is a-coming there's dancing tonight".
