Is this painting good? Why or why not? Any tips from fellow artists? (I’m a beginner.) thank you!

Good things about it: The sky looks amazing. It reminds me of an island, and how you could lean back on the sand and look up to the sky.
Bad things about it:
You could have lightly blended the white into the water. Its kinda hard to understand the middle. ( But its also amazing when people analyzing the picture guesses.)
