@davidrevoy ok, I really tried to consider your points in the painting but I'm too noob it still looks so smudgy.

But thanks again a ton for your comments, those will be helpful in my next try.

I don't believe it for a second
Here is a quick proposal paint-over of what I had in mind if I had to manage the light. Your last iteration (last screenshot) went well in this direction, just the shading of the flowers that could IMO receive a bit more contrast between light key and shadows. And casted shadows. Feel free to pick what you want in this paint-over, and if you dislike seeing the paint over, ask me and I'll delete this message. Good luck!
