That's a great design of the armor. Anime and Samurai meets the Knight.

Looks good! Higher contrast between the gold's shadows and highlights will make it look even shiner and more metallic.

the lineart is really  very good , but you should work more on colors , lighting blend etc ;)

btw , axe light is pretty good

I don't think he's shiny enough. More shiny. Also, I really think more colours would help. Or perhaps just some more varation between your current colours, especially in hue and saturation.

It's okay, I guess. The color choice is good, but not used to its fullest extent, and he's in a weird pose.

thats pretty cool! gold is hard to pull of, but yours is pretty good.
