WIP Wednesday: Handsome Chris Pullover

I'm trying my hand at the Handsome Chris Pullover after successfully (nearly) completing a colourwork jumper.

I feel like I'm going to jinx myself but it's actually been easier than I thought so far and no major issues. I've had to ladder down a couple of times to fix a cable but I can manage that. Only on the back panel about half way through so we'll see how I feel when it comes to the neck at the front!

The pattern seems a bit bare when talking about the arms, does anyone have any experience with making this and have any ideas/advice on the arms?
