Orange Juice (AoI vs Blender)

I created the following scene in AoI. I then exported it, imported it into Blender and rendered it again using Cycles.

AoI Render (Rendering Time: 12 minutes, 29 seconds; Render Size: 1600 x 900):

Blender Cycles Render (Rendering Time: 3 hours, 17 minutes; Render Size: 1024 x 768):

For the marble texture in Blender, I used some of the settings found in this forum post.
