Starting my first dot painting picture

Inspired by my first experiments with dot painting, I rushed out and bought a small canvas to try dot painting my first picture. I sketched out a quick design of Frangipani flowers, based on images from Google. Background all painted black, ready to start.

In my eagerness to get started I accidentally picked up a chinagraph pencil, instead of a chalk pencil, to draw out the design. The chinagraph lines just would not come off, everything I tried just started taking the black paint off the canvas. So, I decided to block paint the background in different colours (hoping this might look more like the style of  Brandon Rollins).

Now I just need to pluck up the courage to paint the dots.
