I literally have no idea whatsoever what it is I am looking at. Way too much visual noise and contrast everywhere on the canvas.
Standard advice; study the fundamentals, paint from life, use reference, go through a proper artistic process with thumbnails (at the thumbnail stage it would have been obvious that your comp wasn't working).
I'm sorry that I can't be more specific with the advice, but since I can't make out what the picture is showing I have to be somewhat general.
thank you, this helped a lot.
