He brought up edge hardness because two details are very noticeably inconsistent:
* the missile bodies' specular highlights show light reflecting as if the missile bodies were round tubes
* the visible edge between the body and nose (cone in the first pic, ogive in the second) and at the aft show the missile bodies are faceted
It can't be both. A missile need not be round, it just needs to be whatever shape fits its launch mechanism, is easy to manufacture, and gets its job done. In most modern real life missile applications, a cyclinder-shaped missile body best fits those 3 criteria.
Second, for those who did not know it before, the explosion in China reminded us that polishing metal to a mirror surface is hard work and can be dangerous. So why does a mass-produced item that only gets used once (each) need a mirror finish?
But, the first thing I would change is that the missile is sitting on a blank white glossy surface. It seems to say, "I made reflections and shadows because I can." It reminds me of the mid-90s art from XCOM3. Back then CGI was such a novelty that it appealed to people, but now we expect realism. I recommend you show the missile(s) in its natural environment, either on a launcher ready to fire or in the (opened) container in which it came from the factory. Such a container would probably be covered with warning labels.
I'm not much of a modeler compared to many of the folks here, but I will use my work to illustrate this last point. Below are Black Market Organs on the left and Artificial Organs on the right (low-res versions, but they are fine for my point):
The containers are exactly the same -- a box with systems to preserve its organic cargo. What's different is the lighting and background -- the black market product is in a dank "warehouse" kind of place, while the legitimate product is in a clean "hospital" environment. I made these images with my work computer while on a trip, so there are mistakes. For example the "black market" wall texture has the specular highlight facing down not up. But the point is that they show the product in a normal setting.
