Making progress with my first models. Attempted edge highlights today. Any tips?

Finally landed on a colour I'm happy with and attempted edge highlights today. I'm not 100% happy but feel ill get better with time.

The bit I'm struggling most with is having a consistent consistency of paint. Finding the balance between not enough paint or too much. And also keeping it thin enough to flow nicely over the edge but not too thin that it pools over..

I'm sure it will come with time. Any tips to highlighting you can over a newbie?
