Very simple basic pose as I made it for something else, but I used it to refine his half-siren design, and as a whole, my half-siren design in general. I made the tail look better connected to the body by actually making it a part of it, edited the fins and tip to better match his/the normal siren shapes and colours, and just touched up a lot of tiny things.
 
What you can’t see is how all the pieces on his head and body are connected properly so they look good even without hair, and the scales on his belly. And trust me, this isn’t needed for normal vectoring, but for references? Very much so.
 
Anyway, expect to see more of him like this in the future.
