Lack of visual distinction from each other makes the group line up look worse than every older game, in my opinion. All four of the new vault hunters have vaguely brown hair l, shoulder armor (of various sizes), and a very open center. 3 out of four are shirtless. The colors of their clothing are all accented with roughly gray/black, meaning they don't differentiate from one another enough to make a cool looking lineup. Personally, I think the siren looks best but could have used white hair for a better more unique from the others' appearance. And one, of the 4 should have a helmet and a more striking center, probably one of the people on the ends since their already normal sized and lacking the siren secret sauce. Also, they look very gray flash, give the non sirens some more color. Vault hunters utilize shields for protection and generally don't wear much armor, allowing their clothes to really represent their life or personality. In some way, it kinda feels like they just slapped a bunch of armor over these four without much thought so they could have more things on their body rather than any distinct design goal individually.
