Really great brushwork and paint mixing. Exciting.
I think the inconsistent part is the palms. I don't know that the trees actually look like where you are, but I would recommend that you at least in part make them more shaped and less stringy. It would be more consistent with the rest of the painting. Right now the way you painted them stands apart and draws attention to a weaker part of the painting, almost like you got derailed in your sensibility that you so consistently worked in the other areas.
I love the sand. Love the vegetation (other than the palms), love the sky, the building in the distance. All that is really great. I especially love how you've accented the color to add spice to the areas with slight variations. I can wander though the canvas and linger in places, delighted with the craft.
I'm also not real sure about figures in the picture. They may be figures, they may be the scruffy bark that falls around palm trees.
Would behoove you to practice a little how to translate various objects into the style of whatever painting you're doing so everything shares the same vision -- just to complete the mastery. These are getting into the excellent category, so you want to make every mark excellent.
I'm impressed at how far you've come. Something clicked along the way and you're on a higher plateau.
