Hi this is coming from my new Pencil Brushes that i am making right now. i am pretty happy with the result bu not 100% .WIP. hope you like it. All the shading is done with the same brush.and the "detail" lines are also the same brush.
This is the idea, to achieve something like the "sketch1" from my Ramon set on mypaint. Old times There are differences so ideas are welcome.

Wow... they're gorgeous (both the brushes and the sketches). All these new brushes are going to make Krita radically more accesible to new users.

I tried to emulate your sketch1 brush too with varying degrees of success lol. Hopefully you, the author of the original brush will have better results. Here's a really... really bad 3 min sketch example of the brush. Not happy with it, but it's close to your brush. Keep us posted on when you get the brush your working on ready for the public
