3D etching on Carboard questions:What sorts of finishing can I make on top of interlocked carboard (123dmaker) to look professional?


 I want to make a 2 meter tall sculpture of a face but
 I need to know what are the possible finishings for this sculpture,  and can I put the borders on stacked carboard and the interior on interlocked carboard.? how do I do that?

is there a finishing that looks as good as this?

maybe crazy textures finishings, do you know any?

this technique is massive in terms of carboard usage, can I use grided technique on the interior?

How would I do that?
