Well, I've remembred that the project is actually about experimenting with different techniques, So after the pixel works I've tryed to mix traditional pencil sketches with vector coloring in AI. And I don't like it at all. Not only because of bad drawings (that's the matter of practice) but I found the process itself rather boring. To clean pencil for digital product is a torture for me and the final piece is nor really good for patterns. But that the matter of taste and habit.
