I have designed the way the crests work for the body. I have come up with a few layout designs for them too.
I'm also finalizing the look of the races. Such the Oongaka are very well built while the Breedo are very lithe and weightless, the Engele are long and streamlined for water travel while the Tyrnias are more average human than the rest. Each have their pluses and minus'.
That being said the costumes are a little different for each race due to culture and physical differences. However they will all be recognizable for what they are.
