Wow, I got completed turned around by the focus on the Priest of picking one when I was reading that it stuck with me when replying about both sets. Whoops!
For the sages, I don’t know if I’d entirely agree with Pikmin that the left sage’s cloak is hard to read around the shoulders, but I do think that both shoulder pads and the far collar (the one to our right) could maybe use some minor adjustments on shading?
For the shoulder pad on our left, it’s mainly the two pixel set of lightest skin tone that kinda makes the leather (or at least what I assume to be leather) feel a little bright, while it’s the bottom left pixel of the “L” shape on the far shoulder pad that stands out to me, personally. (If there was room in the palette for a half-shade in between the (255, 198, 148) and the (184, 121, 84) shades* I feel like it’d work perfectly there, since the latter just makes it a little too dark.)
For the collar on our right, I think it’s more shaping of that part of the collar/cape, and the shading tangentially? Since the body has a slight rotation “counterclockwise” into the screen (i.e. away from the viewer, to the right), I feel like the current placement makes it look to us that both sides of the collar are more aligned with a straight-on angle to the “viewer”, which doesn’t 100% line up with where the shoulder and collarbone on our right would be at in 3-D space? Which, I guess, does also carry over to the respective spot for the mantle on the shoulders (not the cape around the neck) on the right-hand sage as well.
I don’t really have too many thoughts on the sage on the right, though to comment on the hair aspect, you could maybe make it happen by tweaking the colors right along the row where you have the black pixel in the eye (though obviously not changing all of them), but I don’t know how well it’s going to visibly come through at 1x zoom - it might depend on the palette. A long haired version (like if a character with hair like Louise were one, for example) could come out between the head and the cape around the neck, but again, not sure how visible it would stand out unless the palette had a stark enough contrast.
That said, and touching back on the asterisk* I left above, I’m not sure if it just hasn’t been quantized yet or what, but you do have some odd color values at the moment and both sprites are sitting at 18 colors (including the background - at least according to the program I’m using), so I don’t know how much room you’d have to add hair on the sprite on the right anyway, unless it was tied to the robe/cape color or if you changed the color of the trim from the yellowy golds to the skin tones like on the sage to the left.
I do like both designs overall - as I said they’re both pleasant enough that I think they’d easily both get use if finished and made public. I do tend to think that the PoR Bishop-style one stands out to me more, simply because it’s different enough compared to the vanilla Sage, mainly due to the headgear, while the one on the left just feels like a slightly more glammed up regular Sage (even though it does have its share of customization going on).
With the Priest, it’s mainly this spot that I feel is kinda… empty? https://i.gyazo.com/790542fa4cdd53e3df1b1d059a3a6923.png Maybe it just needs a little more of the (75, 150, 211) shade to give the right side more shading for curvature?
