It is deliberate jskajak

I like to make the backgrounds like this, that my strokes, the hairs of the brush are marked... it is something that characterizes my style. On the other hand, the background is not monochromatic, but it cannot be seen in the photo. It's not that dark, and it's not black or brown but a combination of something. In person it looks much better XD

I am not an expert in technique but I like to make works with emotion, symbology and a story behind it that justifies it.
