The painting is on a 80×30cm canvas. I'm not sure if the problem is with the texture, vibrance, values, composition or something else?

The painting is on canvas (didn't know cardboard is better when I started it), 30×80cm, only gouache. I know I should clear out the clouds and fix up the faces of the figures on the left side, the red hair of the bottom right one and maybe touch up the flowers in the center, but I'm not sure if I'm missing anything. Would be glad to get some criticism. Thanks in advance!
