So, I'm working on art for my Harengon barbarian, and I'm unsure on the color scheme, what do you all think?

So, this is Elrik, my Harengon barbarian. A few pieces of info I think could be relevant:

-He was a gladiator before the adventure started, so I want a fairly bright color scheme to make him eye catching, as the gladiators are the focus of the fight

-I plan on having him be path of the giant, and I'm going to take the giant strike feat, not quite sure on which specific variant I'm going to go for, but I'm thinking either Frost or Stone as those specific variants I think would fit best for a gladiator going for an intense fight

-He primarily uses a greataxe, but also has a boomerang and a trident.
