Really like the way this is turning out! I think that for this character, try some mace and hammer designs as well and see if you like those; for his body type, they should be good weapons because they’ll allow him to use his blunt force effectively. He doesn’t really seem like the type of guy to use an a sword because he’ll have the muscle for a blunt weapon and perhaps lack the accuracy for a bladed weapon (if you are going for a beserker-like character, which based on the silhouette and musculature seems to be the case).
Also, viking variations would be cool to see and in fact might take you on a different path. Who knows? You still have plenty of time for experimentation
