What could i have done differently?

Hi, what do you think i could have done differently to achieve a better result in my file Ambulance 3D? I have used a combination of photos taken from my iPhone and Phantom https://skfb.ly/Rr7S

Well ! What is sure is that I don’t want this ambulance to carry me !
How many pictures, which camera ? Seems the right side has benn more “shooted” than others
