Translation and transcription for a tattoo, Khuzdul/Cirth

[Murder Crow]

Khuzdul is a Tolkienian language, and neo-Khuzdul its movie-related expansion by David Salo, as published Khuzdul vocabulary is rather limited.
On the other hand, the Cirth are a Tolkienian writing system which is rather well-known. Indeed, Tolkien has shown you can perfectly use the Cirth to write English.

That said, I've checked your transcription, and it looks like you're trying to use the Angerthas Moria mode. Still, if you check the linked page, you'll see there are three issues:
- You confuse the certh for D with the one for GW (true, they are quite similar) ;
- You don't take into account the long vowels in khazâd and mênu : check the long vowels in the table (they are marked with an acute accent, and are in fact modifications of the short vowels).

I believe I have corrected it. Would it be correct to use Angerthas Moria or should I use Angerthas Erebor? Is there a more correct one?  If it makes a difference, I am using the transcription along with the axes Gimli uses in the movies for the tattoo.
