Made it a bit bigger:
CO 28 for body, increased to 32.
CO 14 for sleeves, increased to 16.

Joined sleeves to body, knit one round (maybe 2), then began the yoke colour work. I changed the yoke pattern slightly. Did not make a sewn-down collar, I just ribbed 2 rows and bound off.

7.5 cm long
body is 5.5 cm wide
