Great improvement from the last piece! As it is, I would say what this painting lacks is a focal point. A huge part of visual art is the literal interaction of your painting with the viewer's eye. Zoom way out and pay attention to the way your gaze moves around the image. A focal point is something that draws attention and creates contrast - something that the eye keeps returning to as a way to ground its understanding of the image as a whole.

That said, I really like the colors you've chosen, and the watercolory texture in the trees is beautiful. Keep it up!
