Still not good enough.
I'm not entirely happy, go change the alphabet until it has the right character to represent the sound I want. While you're there, make a letter for various clicks made with the tongue... I don't mind if you want to use accents of vowels to change it to different types.

Letter for clicks
You could steal the Xh consonantal from the Xhosa language. An inhaled glottal stop.
