Hi! The design is good overall it might just need a small push, I will try my best to give you my take for each of the things you said you struggle with. I think to make him more manly you should it a real small amount of complexion and wrinkles to his face he looks a bit two clean, but very little to not make him look old. try experimenting with the same face in a lot of ways and shapes. 2) try to look on references of how Viking kings used to look like, it would inform your decisions a lot more. 3) I think what the design misses for me the most is the pose, he needs a more interesting silhouette, most of the best character designs are recognizable if you will feel they shape in black, like homer Simpson and even Geralt the Witcher (the two swords on his back). 4) for the clothes, try to search how the materials of the Viking clothes look like in real life, and then try to draw this clothes until you feel like you understand how to convey them. My teacher taught me to look on how things look in real life and then explore different ways to put them on paper.

so here are the spots that im thinking about . also royalty always have very nice daggers so 😄 ehh . also these are optional things you dont have to do any of these things they are just ideas from my perspective.

also about the making him seem more royal. i would make the cape not torn and give him more silver like around the belt. the four arms. and the boots. as well as a silver head band. and maybe some brighter trim around the edges of his cape. i hope that this was useful. god bless and take care. ✌😉

hey. 1st off this looks amazing! and i love everything in both of these pieces. ok so about the young thing in my opinion he looks young enough but i must say that if you want to make him look younger give him less fascial hair like. maybe give him a go tee. i hope that this is helpful. 😉✌✌
