Lamborghini with Arsenal mounted

Everything is created in blender 2.79b
cycles rendering engine
i made this project few months ago as a hard surface practice
First i created that machine gun M134 minigun model, then created aventador
and finally fused them together..
Then i wanted to make car look like like warrior with scratches, cuts , blast impacts, then it is where blender helped me a lot with its texture painting tool sets!
and finally i got this!
However i am thinking to make few upgrades in this scene in future!
