The whole double lower grille assembly is still looking a bit clunky due to the conflicting ‘lines’ that it generates, but it is getting better, yes. Try playing around with ideas to see how you can make multiple fixtures fit into a bigger overall shape so that the shapes don’t conflict.
The difference between trims in mass produced cars is often very subtle or even non-existent. It can even be simply the difference in material of certain bits or the addition of a lip, rarely the change of an entire bumper assembly as that would be costly. Consider the new Civic lineup, has a good 7 trims (VTi, VTi-S, VTi-L, RS, LX, Si, Type R) and the only one that looks seriously different would be the Type R, because it has a whole bunch of functional aerodynamics on it.
