You're throwing loads of terms at me that I don't know - consider an index, making keywords bold, or giving more simple analogies to ease the new person into things, such as "Kshan, the shadow-dwelling nomads" instead of just "Kshan". I got lost with species names through the backstory several times.
The "hats" for the races are good for establishing each race's identity, but just be careful not to paint them so broadly that they just become "the warrior one" or "the assassin one". For example, dwarves are traditionally the warrior people, but their culture is based around invention and trades, so the idea of a dwarven alchemist or a dwarven engineer never feels out of character.
I'm guessing this stems from "draw what you're good at" - I don't blame you, there's a reason my homebrew is based entirely around insects - but try and give the races just one or two visual differences. I'd say at least half of them just look like the same race, with maybe a different tail or a different size. If it's hard to come up with different bodies or faces, then I'd recommend drawing a group shot with clothing, since clothing is a great way to convey a race's culture. "That lizard thing" now becomes "the lizards that live in the desert because turbans and shawls and such", if you get me.
I know it's probably the theme, but I'm beginning to hate the letters k, x, and z now. They're also the go-to "alien" letters. Just dial it back by 30% or so. (This may just be me, though - I still get confused with Space Marine names.)
Lastly, when establishing a race's theme, try to explain WHY it's that. For some, you've done this fine - Vakans are born with huge scythes and horns and pincers, so that explains why they're a violent race - because they're naturally built for it. With others, however, there's not much reason given. For example, why do the Vohra have elemental powers? Is it something they can just "do" or is it a technology or magic that invented? Hertavok can use healing magic, but how and why? Just little things like that. You typically don't need an essay for each thing, just a sentence saying what's needed.
I'm aware there's some hypocrisy with my own homebrew going on there, but I'm not really getting any proper feedback for that so you know (except new suggestions, which are great but not saying if what I already have is good or not.) Also sorry if this seemed like I'm laying it hard, it's just how I do constructive criticism. Assuming you wanted any. :x
