Looking pretty good!

With respect to the crackle paint, I have a few suggestions that you might want to consider:
- Paint a darker colour onto the base first, as this shows through the crackled paint later on and gives a better definition.
- Apply some gloss varnish (polyurethane is better than acrylic IMO) after the darker base colour is on, but before applying the crackle paint. This helps the cracks develop better.
- Apply the crackle paint pretty thickly, preferably with a little unevenness. This helps gives you bigger and more varied cracking, and looks a bit more natural.
- Once dry, mix a little matte medium with some clean water (about 1:1 or 2:3), and paint a good thin even layer over the whole base. This mattes down the gloss in the cracks, and helps the smaller cracked flakes stick a little more firmly so that you don't get any of them coming off.
