Nord alpaca sweater

This is the Christmas present I made for my son.
Pattern: “Nord” from Sandnes yarn. Booklet «Tema 51 Norske ikoner»
Yarn: Puno from Rauma Yarn
The pattern calls for "Fritidsgarn" wool yarn, but he is very sensitive, so I chose to use alpaca instead after recommendations in my local yarn shop. My son is between size M and L, I knitted him and L with this yarn, but ended up a little smaller than desired. He will hopefully use the sweater anyway, he is spending the next 5 months at Svalbard; an arctic island.
