Oh my, Ironstylus arrived! I'll overwhelm you with my thoughts about champions as related to their factions, as I'm a big proponent of the world building approach. I think it is very important to have a common thread through each faction, aesthetically.
Bandle city. Some of the old champions, like
,
,
and
, could use some identity-improvements, otherwise this faction kind of embraces the variegated. Decide on a number of fingers though, haha.
**Bilgewater. ** They are few but pretty consistent; individually the characters deliver their thematic in a satisfying way. Maybe they could use some overall aesthetic development so they are more obviously connected; some common coulours and design-language. Even though it started as a pirate themed faction
feels like a good starting point for their style. Maybe push some of
s design towards these guys as well.
However, not a fan of the cockney vibe from The Pledge.
Demacia. Demacia has always had a strong visual identity. Some champions could gain from being more distinct. 


have very similar tight overalls,
could be more buff than her fragile peers.
feels like an outlier. What is supposed to make him interesting? His visuals doesn't tell much of a story, most of his kit doesn't really deliver a fantasy very well. I think he has potential to be Demacia's answer to
, though.
Freljord
There's already been some great development here. The faction is consistent as a whole, some *individuals *could use some defining.
could use some visual storytelling, maybe an "adventurer" vibe.
could use the same treatment. Try figuring out a way to make the mix of Freljord and Ionia work visually for
.
Ionia
Move
towards
s visual language. I'd liked to see some more obviously Ionian elements on
and
; just some small things. Also elements of
I feel could be improved. I'm no fan of her pelvis-area, otherwise the clothes are fine. It might have been a lost opportunity not to juxtapose her body-type with her "power"-theme; a shorter, more svelte frame would have been a nice contrast to her OVERWHELMING POWER. Currently she looks very tall because of her tiny head.
Noxus
The new aesthetic identity is great!
currently don't fit in at all, though.
(
in particular I'd just move straight to Zaun) 
are almost there, some light work with their aesthetics would really bring them home.
as well. He could also benefit from more practical weapons though; the wrist-blade looks clunky, as do the bladed cape-weights. A better delivery on his arsenal would be great.
Piltover
needs some tech- and fashion-upgrades, otherwise these guys are fine! If you keep some yordles around this place make their tech match the area.
Zaun 
need VU's.
should be more alchemical. Industrial alchemy could be a common theme for this faction. And if you ever get back to
, make him more machine.
Mt. Targon
needs some visual development, otherwise we just need more stuff from there! Maybe put
there and push the greco-roman angle?
The Void Thematically the place is good.
and
could do fine with a
-level update, but try adding a touch of Shurima to their designs.
Shadow Isles 
need to adapt to the new awesome visual style!
Shurima I love the new Shurima, but 
Don't fit in anymore, and they fall kind of flat anyway.
needs an identity and something other than green bandages; also don't make him a yordle for goodness sake.
is charming, but make him visually more Shuriman, through his armor for example.
's shapes are crude, especially the tail. Work him through and put some other materials in there, like duller rock; something that indicates a desert-dweller. Also try other ideas for his face, something with more intelligence.
Others
Give
homes! Or at least develop their characters, give them history, give them purpose and connect them to the world! There are many good themes here, but they lack context. I'd want to see
and
developed, especially.
I love
, but it bugs me that she wasn't pushed more towards plant. Try scrapping the fleshy parts and "leaf costume" in favour of building her body through-and-through out of thorns, plants and petals. Her silhouette could also be pushed further into rose-territory. More thorns, more agressive shapes!
There, ask if you want more thoughts about any of that!
