Post work over 3D CG animation (LW3D): 
Using Project Dogwaffle Timeline filter FX

[ back to anims ]

original and after post work:
Dino original
cropped to rectangular selection, then snow storm fx/rain mode applied through timeline editor
another set of tricks:
oval alpha mask, inverted, then flood fill with max tolerance
rain/snow fx through alpha mask only
convert to greyscale (timeline filter fx)
motion blur with variable direction angle and intensity to mimic camera jitters due to ground shaking
camera man focusing in on dino's eye (manual transform in timeline). Also added a bit of embossing for more 3D depth
