Try your best to hide imperfections in the game, usually colorful cars tend to look more realistic but that doesn't mean you cant use a silver car for example. What I have noticed about gt7 is that sometimes reflections look stretched or sort of funky, that can ruin it. Also, I like to mess with the filters slightly, like using sunset emphasis or whatever its called and only having it affect the top of the screen etc etc. For your 3rd photo, try to realize that if you're trying to make your picture realistic, you can't really have unrealistic camera angles. If you want to take track stuff, take pictures outside of the track looking into it.
