It's just a lot of practice Quickchange & you're doing very well..Pinstriping is like anything else & the more you do of it the better you get..It's easy to tell that you have some familularity with a brush & I imagine this came from your work in porcelain..I never could find a place that paid me for pinstriping so I stick with what pays the bills..It's still fun to mess with though if only for pleasure & a change of pace.. You show so much promise that I'd advise you to stick with it..
It's a little bit (a whole lot) of a mind game..You start to see the brush stroke just ahead of the bristles & with your head & a slight twist between your fingers you can control every hair in the brush..sounds crazy but that's what it is..You should feel very good about your practice..It's a lot easier said than done & you've done a pretty job on both..
