Looking really nice Thomas.
I'll add some comments here for you:
The shoulder silhouette could be a bit nicer, feels flat-ish.
Forearm silhouette looks a tad broken
Might be nice to see the armpit pocket revealed in this pose
On the pecs it's important to have the pec pull straight when the arms are out, otherwise you don't get the right shape in the skin.
I realise I might not have addressed these in my own version of this asset, but none-the-less will mention here.
There's some stuff to consider anyways!
