This model was built by me back when I was learning blender and wanted to do some serious work. Achieved my goal of modelling something serious and sticking with it but sort of abandoned it for a while. I’ve decided to give this another try and change couple of things to make this a perfect model. I still have to figure out texturing and different types of materials and of course, composting. I’ve been using blender for a while now and I still have a lot to learn. Tips on Materials and texturing will be appreciated. 
Yes this is the truck of Optimus prime from Transformers also known as Peterbilt 379.
My computer isn’t the best out there, actually it’s horrible. Takes 10-15 minutes just to render something really simple but I am spending a lot on the next computer as i will be costume making it for quick rendering.
This was rendered using Cycles.

Do suggest improvement and leave some tips for texturing/materials for the truck. Thank you in advance
