Edit:The text says, going clockwise from the top:
- Vorlon-esque head + shoulder region (Make more insect-like[?])
 - Fix this joint area
 - Put some sort of finger here
 - External ribs, barely above the hardened chest [plate]
 - Back plate/shell?
 - Segmented abdomen
 - Chicken legs
 - Maybe add some long spines/hairs sorta like the Protoss have?
 - Symmetrical, obviously
 - 3 toes
 - Jagged thingies
 
Another, better quality picture:
Official (diplomatic) name: Azaru (
subject to later change)
Technical name: Mantisidae
Colloquial names: Mantis, Bug, ... 
maybe more later ...
A humanoid/insectoid alien. Technologically advanced, but still uses melee combat extensively (although not exclusively).
And now another sketch, same alien. Some changes, some maybe temporary, some approaching final.
Edit:See next post for sketch #2.
