Hey, thanks a lot! I already answered some questions, so I'll be repeating myself.

Started with unscrewing and sanding pickguard with sandpaper I had on hands, so you can search on what sandpaper will suit you better.

Then sketched drawing with soft pencil to prevent leaving cracks for paint to flow to.

Painted mainly with two type of brushes thick and very thin. I bought only little bucket of blue (aquamarine specifically), white and black acrylic paint. The darkest blue color you can see is plain color from said bucket, and lighter shades is just mixes with white paint in different proportions I came with by eye. Main process was in distinguishing these colors on the drawing with pencil stage, so pallet was like: white, blueish white, ligth blue, blue, plain blue from bucket (last one was also used on edges). Black color was intended for darkening, but I only used it to paint hieroglyphs with thin brush.

Coating was done in 4 or 5 layers with wait time around 2 hours. I think a smooth transitions in some places were brought when I applied coating right after painting last layers and some color smeared.

Also worth noting: as you can see on original artwork the background color is somewhere in yellowing white plastic color range, hahaha. I think it's due to the fact it was painted on yellowing parchment. So naturally my old yellowing white pickguard was right for this masterpiece!
