After looking at the Featural scripts of some conlangs, I decided to mix them.
There is this one video by someone in response to Jan Misali's admiration of seximal, their video being about binary. I decided for my mixture to include a system based on their custom one, with a small circle for zero.
I have some ideas for modifying the grammar, though Shmili didn't flesh out the verbs of Dorini. I'll need to ask him what there is to know.
There is also this video by Lexis.
It inspired me with some ideas for phonological inventories.
(That one with the ejectives and the edition of the palatal and velar fricatives, I'm still debating on the syllable structure.)
It's a lot of ideas, and I have some for the grammar I intend to flesh out. Lexis listed some example inventories that I decided to modify. The others are protolanguage ideas. I'm thinking of various humans speaking these languages after looking into the types of groups the Creek Kids from Craig of the Creek could be divided among, and from thinking about the Age of Shapeshifters storylines by Syfyman2XXX on DeviantArt.
One of them mixes Ts'ap'u-K'ama with Proto-Eskaleut, so I might consider modifying a Bantu class system like what Biblaridion said his conlang would involve and adding modified editions of Proto-Eskaleut grammar, with the polysynthetic nature retained.
Another one is a mix of Proto-Austronesian with Proto-Sino-Tibetan, with the addition of clicks. The grammar is intended to be a modified edition of Austronesian alignment, and I plan on looking for the proper videos to understand that, and the operations of Austronesian alignment in the protolanguage.
I also need to think of the taxonomy of the speakers in terms of their categorizations of animals, colors, and so forth, remembering that video by Lichen.
The following chapters will flesh out the ideas and the grammar more thoroughly. Somewhat.
