maybe the scale is right now but it didn't look right.
In the first pic i would guess the bottle is ~25cm, in second i would guess it's 1m
I don't know how you fixed the DOF but i guess you made the scene bigger till the blurriness was gone.
If yes - don't do that, if you want the bottle in focus you have to edit the focus distance.
(imo the background should be a bit blurry)
What programm did you use to export your scene to indigo?
I'm sure here are people who would explain you how to set up the focus distance
within your programm. (i could only explain you the way in C4D).
Futhermore i think the proportion between the bootle and the scene, and between the bottle and
the ground-texture isn't right.
Otherwise really good so please keep it up!!
Half of my post was guessing so i hope you don't mind if i were wrong.
BTW: where are you from? never heard of Brahma
