Hi, BaronSat - I think this is very good!
I found your model photos immediately when looking for Bantha images, and they've been just what I needed. I wanted to estimate the area of fur fabric needed for a Bantha model (I've been trying to work out possible sizes). For this, the visible stud-unit dimensions of your model are ideal.
The scale relative to the minifigs looks OK to me. Of course, Banthas had to start small as calves then grew, so depending on their imagined age and the age of the Sandperson with them, various relative sizes could be feasible. But Banthas are supposed to add one section of horn per year's growth, though, so a Bantha with those full curved horns (as seen in the films, or your model) would likely be 35-40 years old and really BIG! (They used a disguised elephant for the first Bantha filmed.)
A young Bantha calf, though, could be relatively much smaller - and have proportionally shorter horns, even just bumps for a yearling (something easy to adjust, in any Lego model.)
I like to think about these details
Thank you!
