I used needle size 2,5 mm for the twisted rib (body and sleeves).
Needle size 2,0 mm for the neck rib.
Needle size 2,75 mm for the rest.

I made the following changes:

Body:
15 extra rows between waist and bust shaping.
Length from cast-on edge to underarm: 42 cm.

Sleeves:
Sleeve length to underarm: 48,5 cm.

Neck rib:
I worked twisted rib for 7 rounds instead of 10.

The pattern is very well-written and easy to follow.
