What does that mean? What does "too colorful" mean? What is the right amount of colorful? What is a cartoon look? What is a proper, non-cartoon look?
Non cartoonish armor design : On spoiler : Gothic and Dark Souls Faraam set
Cartoon armor design : On Spoiler : DOS2 and D3
Armor doesn't need to be realistic(eg : greedfall) to be "non cartoonish". Faraam set is a fantasy armor which is gorgeous IMO. On Dark Souls 2 and 3.
