I’m starting to draw a BGA but I think the stroke is very thick. I do not like this as it is staying.

I’ using:

Clearance --> 0.1 mm
Track Width --> 0.1 mm
Via Dia -->0.4 mm
Via Drill --> 0.2 mm

Normally what measures are used?

I remembered some BGA tool thingie from a recent post.
A simple search & re-found it in:

Have you looked at some other BGA related threads on this forum?

Your footprint looks weird, but I am unfamiliar with your color scheme.
Yellow is the copper I presume, and purple the solder mask ?
The pads look much too small and exposed copper on the traces seems … unacceptable.

I’m not very familiar with BGA’s, but I think it is common to use 6 or more layer pcb’s and (micro / buried) via’s to fan out the pins, just as in other posts here. That seems to be the only way, you are never going to get more than 2 rows of the BGA fanned out per layer.

You also may want to have a look at the Olimex Olinuxino A64 design on Github.
It is a fairly dense PCB with several BGA’s done with only 6 copper layers in KiCad.

Looks like a screenshot of the 3d viewer to me?
The NPTH where the tracks cross gives it away.
So realistic colors with purple soldermask and golden copper.
