orc descriptions for TT

Alkett:
The taller of the two, and the broader. Muscular, with dark greenish-grey skin, the colour of lichen.
Descriptions of her from the story itself:
Two long scars curved from the corner of her left eye to her broken left tusk. Her left arm was a stump capped by a machine-- a clicking, whirring mass of grinding gears that stretched to a metal hand with long, clawed fingers. She wore her arrakos [a dark lace veil- I was thinking of Spanish mantillas] low, and it was tattered and torn, a shadow wrapped around her shoulders.  Jerboa skulls studded her helmet, gleaming in the faint lantern light. A small pack hung in front of her axe sheath, and a coil of rope hung from her belt...
A puff of steam hissed from the pipe at Alkett’s elbow. She turned her arm and fiddled with a gauge.

Karvek:
The shorter of the two, and built scrawnier. More like a Tolkien goblin than a Tolkien orc. Hunchbacked, bowlegged, wary-eyed. His skin is grayer than Alkett's, and his eyes are golden. His head's bare, with a stereotypical Orc Topknot.  He's also wearing an arrakos and he's less heavily armoured than Alkett.
