Armor

There isn't much exploration, I agree, but I'm not sure what you mean by the limited amount of armor designs as there are tons for every character. There's lots of different kinds of cool heavy armor like the stone armor, the iron golem armor, Smoughs armor,
and the iron armor. There's lots of cool medium armor like the elite knight armor, the armor of thorns, the armor of favor, the armor of the glorious, the eastern armor, and Orenstien's armor. And there are tons of light armors like the two normal and black
leather sets as well as the shadow armor, the gold hemmed robe, the armor of the sealer and a couple magition armor for sorcers. I didn't come close to naming them all.

Armor, armor, and more armor. Did I say armor?

Lets just compare torso armor for a second. Daedric offers a base of 49 Armor, Dragonplate is 46, and Dragonscale is 41. These numbers are affected greatly by perks and skill level. It behooves you to wear matching armor sets, the perks "Well Fitted"
(Heavy Armor, 25% bonus to armor if head, chest, feet and hands is heavy armor) and "Matching Set" (25% bonus to armor if all armor is of the same material) are great. Throw in "Juggernaut (Rank 5)" (Increases armor by 100% at rank 5) and that is 150% armor
just in perks. Light armor has matching perks, but as base armor for light gear is always less than heavy, Heavy armor will give you more armor in the end.

I have 4 Wolf armor, Nightingale armor, ancient nord armor, Then dragon scale armor

if you want revealing armor, you would want Fur Armor (with no top), the Savior's Hide, Forsworn Armor (a better version would be Armor of the Old Gods), or the Falmer Armor.
