This was a hard one for me! At the moment I'm trying to look at the picture longer and trying to think in advance what would be the best way to approach this. And then translate it to my hand and paper π€£π A lot can go wrong but I stop fiddling around with this now. Please leave some feedback
As long as you see it in front of you, it is one of the most important things. It is maybe frustrating, but what you see in your mind will appear over the years on your paper. It happened to all of us. What I see in your painting is a bit of missing out in colour mixing. It needs more variation in cool to warm, and light to dark. But that will come! I made many years ago an article where you struggling with. I realised it will come in time, but it took me a long time!
