I use more layers in these, then merge them together and add more layers. A slow and repetitive process, but might be the difference. A lot of my other work is one or two layers and I paint it like a physical picture. When I first started sharing stuff here, I wanted to be accepted by the physical art community, so I'd paint digitally, but like them. Using so many layers and the mirror tool like this is leaning much closer to the digital art world.
I'm glad you like it.
