I am a big fan of the main quest characters. They are part of my first memories of ESO as a newbie, December 2014.
So, I was quite glad seeing the outfit pages for these characters.
However, if you look at the following picture, the Prophet's cowl is to flat. It looks like my char has no hair at all, but also like her head top is flat like an anvil. From what I noticed this outfit does not have a sash piece, so I used an Argonian one, but I think it is no trouble to add a very simple sash or even an invisible one (which many people would appreciate, btw). Anyhow this outfit will probably be one of my favourites



At this moment I don't have the tools to put two pictures side by side, so I included the Sai Sahan costume below, which does not have a head piece. Speaking of it, I think it is great, even though the shoulders are not linked to the chest piece in any way. I would remove or the floating hip flaps to make it perfect or somehow make the flaps part of the leggings.
The other 2 outfits are somewhat underwhelming. Tharn's outfit is very similar to the one we get at cp 160, and the Titanborn's outfit is so similar to other Nord costumes already in the game.

Caldwell's weapons are amazing!
I really like the original and funny concept of these weapons! The bow quiver is probably the best!
