Yeah I apologize it was really late and the computer was being gay...anyways, here's the phonology for both, which I put together this morning.
Wish my computer were gay, but I'm pretty sure mine is asexual.
ǚ: this a nasal vowel, I’m not sure what it’s called but it’s very common in Cherokee and other Iroquoian Languages, like in the Cherokee word vganuweuwe, or anyvnwiya, and in these languages it is represented by a v. This sound is absent in Calderish.
Nasal schwa, that's what it is in Cherokee at least.
ħ: pronounced like in German Rauch, or the way we pronounce a j in Spain.
ĵ: I don’t really know how to describe this one. It’s sort of like how a lot of us Spanish speakers will slur a y and make it into a slight dzh sound, but it is made by pressing the middle of the tongue to the roof of the mouth. I think it’s called a palatal ejective.
For your ħ you want either /R/ for the German R, or /x/ for the Spanish J. For ĵ I think you want /ʝ/, the voiced palatal fricative, one of my favorite sounds.
Anyway, have you ever thought about making a phonology with X-SAMPA or IPA? It's a lot easier to read and comment on, and you can see whether the phoneme inventory you have is normal.
