This was done on a semi-windy day with some surf coming u onto the sand and some blowing sand - which helped give the painting some texture!!! :>)
With a brush I throw in a rough sketch of the scene.
Next I throw in the sky indicating the type of day it is
Working quickly - I throw in the trees and some of the sandy beach area
I start building the ocean and indications of the waves coming into shore with some foliage adjustments a tweaks here and there
This was painted with a 1 1/2 inch brush that I picked up this morning at Home Depot for $2.48. Wash it out good with dish detergent and comb it out to dry and it will mostly likely last me 6 - 8 months to a year. The brush on the right is a #18 filbert brush which I used to sketch the scene and for some tweaks here & there.
