Sorry for being harsh. I made a little explanation of how i do my Painting style + Brush settings i use. Example of painting style: [link] Tutorial:[link]
For this sketch i used the tool "Crayon" on size 2.3 pixel. Min Size: 70 % Structures: Spread 42 Paper 58 Blending: 0 Dilution: 0 Persistence: 100
How i dre it: At first i was making a rough sketch, then i made more clear but also sketchy lines. After colouring with a dark sunset like atmosphere colour i coloured the inner lines in a lighter colour.
