I agree, the render quality is quite good for an airbrush pattern on a trailer.

Now try to paste your render into a real photograph and let's look how real it still looks...

custom made morphs don't really show much about the quality of the base mesh, because so much can be ironed out with a custom morph. So this argument is moot.

I'll skip your further comments, because you seem to contradict yourself.

Also learning how to do proper lighting is also a must before trying to come for someone that has more experience than you.  

I suggest you challenge BagginsBill then. Looking forward to that thread :D

But of course, for a super professional as you are, it shouldn't be a problem.
