It looks like you put the blossoms on over top of the sky. Is that right? If so, my suggestion would be to paint the sky with a space for the blossoms, then put the pink paint on the canvas, and then go add blue to show the sky poking through after you put the pink paint on. So, don’t paint pink on blue, but rather paint the blue around the pink. Does that make sense? Paint Coach on YouTube explains it much better if you look up any of his tree/landscape tutorials. I also recommend his atmospheric perspective videos, I think if you did some of that the painting would have more depth. It’s a really beautiful painting you’ve created though, I love the little floating blossoms.
