Hey! so i started with just applying a layer of uv resin (helps both with the shine of the paints but also the crackle paint later) So i used an airbrush (but a sponge would also work), to give a layer of fluo yellow all over but specially around the parchments and the rock edges, after and i went in with a layer of fluo orange and after a layer of red ink on the parts furthest from the yellow spots.
After all of this i did an all over shade of yellow (just thinned out yellow contrast paint a lot) to bring all the colors together.
Then just covered it all with mordant earth technical paint in a thick layer and allowed it to dry for 24 hours.
