OK, I will give it a whirl from what I have seen.

You already have your style and process. I believe you could benefit from exploring different techniques or even mediums. 
I notice you post other famous artists work, I assume you draw inspiration from them. Maybe try adopting their techniques, or use of color and see how you can incorporate that in your own art. I am personally trying to do this as well. Because I feel I've hit a wall.
Also try playing with contrast, and the rule of thirds to keep people engaged. I think your paintings are beautiful but there seems to be only one focal point. It could be a fun challenge
