How do I create Brushes that are not blured?

[Papa Mike]

Thanks for any advice, but the problem is not how to get the drawing into Photoshop.
I've done the drawing, and then used the standard "create brush" thingy Photoshop provides for that kind of task. I always thought this would be a simple task where nothing can go wrong, but obviously I'm doing something wrong. Here is an Example so that you guys can see what the problem is.
The left hill is the original which I used to create the brush, the right one is created by that brush. No scaling or dynamics involved, but its blurred and I don't know why and how to fix that.
