I like the tutorial, and thank you for it, but I want to know how did you make your stroke in step 5 so smooth? mine doesn't look like yours and it looks sloppy:
actually I don't quite understand step 5 too well.
On the step where you said apply soft blur, I don't see soft blur in my filter section, so is it ok if I use Gaussian blur instead?
Get into the brushes dialog and change the spacing on your brush.
