I think it's the way that you flesh out the faces/skin tones so they become 3D, but the abstract shapes are bright and 2D. It's similar to Klimt, but not exactly the same at all!
I keep coming back to your page, it's such amazing work and very inspiring. It would be fantastic if you had an FAQ page that explained the paints, materials and other tools that you use. And if you had prints available
Please keep painting, your work is so beautiful and I desire to have it on my wall
