Just sending random updates, as you can see, when mapping, often you work on the same things, new textures, new styles, new angles. Often you spend a lot of time doing the same thing over again, but differently. But in the end, the result of that pays off imho.
The main object now, is to add colors to a predominantly grey looking map. Not by adjusting textures, but by adding details such as pictures in color. That often gives the result that a grey looking map can indeed be colourful if these addons blend in well.
