Ice cave animation with camera fly in Blender (VIDEO)

Hi. This is mine first animation in Blender. Model itself i have done in Blender, but texturing, lighting and camera movement i did in After Effects and Element3D. Sorry for not smooth, little bit choppy camera movements)

Render time in After Effects - 1 minute.

looks nice, but you have the animation graph set to linear where it would look better a beizer

Thanks, will bear it in mind.
