I agree and must appreciate your observation regarding rear bumper design, but cant do it now as they have already made the light positions. Though you are right that it must have improved alot the overall look from the rear. But cant redo it due to shortage of time and energies of the fabricator as he has already done it twice
Yes i like the finishing and strength of the front bull bar, Thats a piece of art which you must see along with physical inspection of roll cage and its finishing is a treat to watch
No there is no inner iron sheet planned in doors and just a waterproof upholstery is decided in design, however after your question i am thinking to install a cross bars inside the doors between the outer sheet and upholstery for safety of passenger and driver from any side collision.
