Good Job on this Unit odintheking...I especially like the Spotlight and Gun Flash you use with the Attack.
Recommendations: Either Remove the First frame for the Run animation or render the Run again with 10 separate frames. The First frame is a duplicate of frame 2 which causes the hesitation.
The Death could use 100 Flc speed to prevent the abruptness of his fall or add one more frame to his fall before he hits the ground.
Also, It would look better if he was totally on the ground. Use the Drop to Floor button in poser or manually drop the unit to the Ground. The shadows underneath him cause him to appear slightly floating.
