Hello and welcome back!
Taking a lot at your painting I can see several key points that I believe may be of use to you. Firstly the light on the head is more akin to moonlight, as if she is sitting in front of a window. Is that something you are going for? If not then the light hitting her face would be warmer.
I think what could enhance your painting is a stronger face brimming with some emotion. Right now it seems like a women just sitting down enjoying her evening, which is fine if that is what your going for. I think some story would add to your painting.
I am not exactly clear what you are trying to show here, if you could illuminate that, I am sure I can help you more.
On that great road, always and forever journeying forward to that shining city on the hill.
