How to paint a simple flower ~ Cup bottom ~ #StayHome and paint

Hello from Slovenia!
This reverse flower dip on cup bottom is on 12x12 inch canvas and I wanted to have my flower little off-center. I have to work with a straw a little bit on my flower edges, but the final result is beautiful.
Colours:
- Black
- Phtalo prussian blue
- Azure blue
- Greenish blue
- Pearl white
My pearl white mixture:
1 part Vallejo pearl medium
1 part titanium white
2 parts pouring medium
I mixed my paints with my pouring medium:
- 4 parts pva craft glue
- 4 parts acrylic primer
