First off some responses:
1. I think roads in captured cities should automatically become trails, the Cualli aren't going to be maintaining them as roads, so they'd get all overgrown and trail-like
2. Not sure I like the priests of (forget the name) relying on gems, too much overlap with RoK there and no flavour reason that I can think of.
3. Don't really like the LH, didn't look very good quality - I prefered the one of the draconian with its wings editted off (if it had a darker background)
4. Dislike the cavalry units. I think the Cualli are pretty strong as it is without getting free (dont require horses) cav. units, and the units themselves looked quite poor quality (no offense whoever made them). Also, I can't really imagine all those dinosaurs roaming around erebus - I really, honestly think it would be better, more balanced, and more flavoursome if the lizzie civs cav. units were riding horses.
1. i agree with this.
2. i disagree. Slyvann is right that i think it represents obsidian and other presious stones. plus if you look at their sword its inscribed in red letters (i assumed rubys for some reason) so it makes sense to me.
3. the draconian one without wings is already used for the Mazatle leader, just with recolouring and a new back ground (compare the 2).
4. the cavalry still require horses. i couldnt build them without horses. and they look fine and fit the theme fine. i like them.
i found bug. it somewhat critical. Meskiwaki (Chislev hero) aviable to build for all races. I see him aviable to build with Mazatl.
i was alao able to build him as cualli.
More about Cualli - i think all that terrain vitalising and changing to wetland is bit... too much, just very fast and free vitalising.... May be still plains should not convert to wetlands, and grassland > wetlands conversion should be bit slower?
With all that food i can just cut out my pop and build very very fast. With no weak points and insanely strong disciples.
May be disallow to their metal units to use bronze/iron/mithril and instead of it make Sacrificial/ Blood Gem Gems made weapons promo (+2 with gems for swordsman) (like priests use)
the teraforming and the slavery fit perfectly with cualli. the high food from swamps gives them losts of pop, and then the blood and sacrifices civic allows them to cull the pop. i never had a city over pop 7 in my game (except my capital) because i had to maintain happyness, and sacrificing pop was the only way i could. plus it helped with building production nicely.
i didnt find this overpowered as in my last game i was sitting on average points with both absaroke and keelyn way ahead of me in points, and fearyl not far behind.
1. they've got unique religious buildings, yet the leader is agnostic, which means you have to wait for an other player to found the religion and spread it to you. Starting with religion instead of nationhood all adds up to this. My suggestion: lose the agnostic
2. they get double movement through jungles, but not through deep jungles.
1. when the civilopedia entries are put in it will all make sense to you
. plus you dont need to found the religions for their 2 unique temples, you can build them both straight off the bat
2. i found that they actually get double movement over all jungle and wetlands terrain. i may be wrong though...

Now my other observations:
1. Cualli and mazatle are never hit hard by blight. they are probably the safest civs from blight in the game, more so than Sheime (cant spell it). why? because the swamp benefits dont get removed like other food improvments. other civs lose their farms, but the swamps act exactly like farms anyway, thus no (or very minimal) food loss. im not sure if this is a good thing or bad thing, just thought id point it out
2. the Cualli world spell does not grant free civilian specialists to captured cities. i captured a couple of barb cities after i cast it and they didnt get the benefit, but my new settled cities did.
3. i was never able to give my priests more than 'empower 1' using the troop sacrificing mechanic. how do you get higher levels of empowerment?
4. over all the cualli are a very enjoyable civ to play, and i think they can be very deadly if given the chance and if they are played well.
