Placement help please

[angel87]

Hi all
I have been sent this picture and I am just wondering how to get this effect.
She has virgin hair and is a base 8.
I was originally planning on using bleach with 20vol but now I’m wondering if I could even use bleach with 10vol.
But my main issue was foil placement and technique. Any suggestions would be great [emoji106]
Thank you!

I think there are maybe 4 different colours in that picture. I would probably use 2 bleach to 1 tint and diagonal foils.
