As for the window reflection its from the base image so i don't see why should i change that when i didn't chane the backgorund also i will add a light on the groud from the headlights also will do the door to be lighter

Still, what it "is" and what it "looks like" can effect your final result.

dobro je čak i ovako, samo da, stavi refleksiju na vrata i samim time ćeš posvijetliti, prouči crne aute pa ćeš vidjeti kako i šta

I did some modifications and changed the rims what do you think of green one's?
