Here is old vray animation project reworked to new version with Corona Render.
DAZ 3d Animation tools, Z-brush, 3dmax and Corona render/
post AfterEffect+ DFX filters and Copilot/
DOF and MB from Corona///
Post’s are welcome
thats pretty cool.. well done on the render and animation suits for cinematic games. 
Thanks CGDIGI
it’s nice to hear, especially from you///
My only complaints would be:
-low resolution
-strange eagle’s head movement
Full HD only for sales on Video Stock’s, as ShutterStock and others////
This Preview version for YouTube///
Strange movement/// mmmm…
This reference also with strange movements :)???
The two kinds of movement are completely different in terms of speed, axis, and range. The real life eagle looks like he is basically taking quick looks in some specific direction, like focusing on prey. The one in your animation looks like he is shaking off some water or bugs off his head and it is twisting its neck in an unnatural manner.
in truth eagle can twist his head during the flight as he wants, /not only straight ahead, following specific mathematical formula or AXIS and RANGE, and TERM’S OF SPEED :))) /- as seen from the large number of examples 
OMG, i could watch such video all day long…
here better example with what speed he move head, he just looking at targets not shaking his head, it is same for all birds they can’t rotate head so slow it reflex of something, like sparrow always jumping

OMG Bilbo Baggins view videos
/offtopic ended
thanks for post’s, Guys, I completely agree///
First version, /not present here/ was with jumping movement of the heads, i have remake some key’s in for next version(Bilbo Buggins landing on the Rock)
